Hans R. Camenzind (1 January 1934 – 8 August 2012) was a Swiss electronics engineer, famous for designing the 555 timer IC in 1971 under contract to Signetics. He was the inventor on 20 US patents. Camenzind also wrote three books and numerous technical articles, and lectured at the University of Santa Clara.
Camenzind was born and raised in Zürich, Switzerland, where he went to college. In 1960 he moved to the United States, first receiving an MSEE from Northeastern University and then an MBA from the University of Santa Clara.
After six years doing research in the laboratories of PR Malloryin the Boston area, Camenzind moved to the West Coast to join Signetics, later acquired by Philips Semiconductors, and now spun off as NXP Semiconductors. But two years later Signetics lost its way and Camenzind took a leave of absence and worked from home. He then started Interdesign, a semiconductor design company, which he headed for seven years before selling out to Ferranti. Following the sale of Interdesign, Camenzind became an independent analog IC design consultant.
During his career Camenzind designed the first integrated class D amplifier, introduced the IC phase-locked loop, invented the semicustom IC, and created the legendary 555 timer. By 2006, he had designed 140 standard and custom ICs.
Camenzind wrote three books and numerous technical articles. His last book, Much Ado About Almost Nothing, published in February 2007, is a general audience book about the history of electronics. Other books include, Designing Analog Chips and, under the pen name John Penter, he also wrote, Circumstantial Evidence, a book about religion.
An integrated circuit or monolithic integrated circuit is a set of electronic circuits on one small flat piece of semiconductor material that is normally silicon. The integration of large numbers of tiny MOS transistors into a small chip results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. The IC's mass production capability, reliability, and building-block approach to circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones, and other digital home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs.
The 6800 is an 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System that also included serial and parallel interface ICs, RAM, ROM and other support chips. A significant design feature was that the M6800 family of ICs required only a single five-volt power supply at a time when most other microprocessors required three voltages. The M6800 Microcomputer System was announced in March 1974 and was in full production by the end of that year.
A programmable logic device (PLD) is an electronic component used to build reconfigurable digital circuits. Unlike integrated circuits (IC) which consist of logic gates and have a fixed function, a PLD has an undefined function at the time of manufacture. Before the PLD can be used in a circuit it must be programmed (reconfigured) by using a specialized program.
National Semiconductor was an American semiconductor manufacturer which specialized in analog devices and subsystems, formerly with headquarters in Santa Clara, California, United States. The company produced power management integrated circuits, display drivers, audio and operational amplifiers, communication interface products and data conversion solutions. National's key markets included wireless handsets, displays and a variety of broad electronics markets, including medical, automotive, industrial and test and measurement applications.
Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), is a category of software tools for designing electronic systems such as integrated circuits and printed circuit boards. The tools work together in a design flow that chip designers use to design and analyze entire semiconductor chips. Since a modern semiconductor chip can have billions of components, EDA tools are essential for their design.
The 4000 series is a CMOS logic family of integrated circuits (ICs) first introduced in 1968 by RCA. Almost all IC manufacturers active during this initial era fabricated models for this series. It is still in use today.
Federico Faggin is an Italian-American physicist, engineer, inventor and entrepreneur. He is best known for designing the first commercial microprocessor, the Intel 4004. He led the 4004 (MCS-4) project and the design group during the first five years of Intel's microprocessor effort. Faggin also created, while working at Fairchild Semiconductor in 1968, the self-aligned MOS (metal–oxide–semiconductor) silicon-gate technology (SGT), which made possible MOS semiconductor memory chips, CCD image sensors, and the microprocessor. After the 4004, he led development of the Intel 8008 and 8080, using his SGT methodology for random logic chip design, which was essential to the creation of early Intel microprocessors. He was co-founder and CEO of Zilog, the first company solely dedicated to microprocessors, and led the development of the Zilog Z80 and Z8 processors. He was later the co-founder and CEO of Cygnet Technologies, and then Synaptics.
The 555 timer IC is an integrated circuit (chip) used in a variety of timer, pulse generation, and oscillator applications. The 555 can be used to provide time delays, as an oscillator, and as a flip-flop element. Derivatives provide two (556) or four (558) timing circuits in one package.
Silvaco Group Inc. develops and markets electronic design automation (EDA) and technology CAD (TCAD) software and semiconductor design IP (SIP). The company is headquartered in Santa Clara, California, and has a global presence with offices located in North America, Europe, and throughout Asia. Since its founding in 1984, Silvaco has grown to become a large privately held EDA company. The company has been known by at least two other names: Silvaco International, and Silvaco Data Systems.
Signetics was an American electronics manufacturer specifically established to make integrated circuits. Founded in 1961, they went on to develop a number of early microprocessors and support chips, as well as the widely used 555 timer chip. They were bought by Philips in 1975 and incorporated in Philips Semiconductors.
Integrated circuit design, or IC design, is a subset of electronics engineering, encompassing the particular logic and circuit design techniques required to design integrated circuits, or ICs. ICs consist of miniaturized electronic components built into an electrical network on a monolithic semiconductor substrate by photolithography.
A linear integrated circuit or analog chip is a set of miniature electronic analog circuits formed on a single piece of semiconductor material.
Maxim Integrated is an American, publicly traded company that designs, manufactures, and sells analog and mixed-signal integrated circuits.
PSoC is a family of microcontroller integrated circuits by Cypress Semiconductor. These chips include a CPU core and mixed-signal arrays of configurable integrated analog and digital peripherals.
Robert Allen Pease was an analog integrated circuit design expert and technical author. He designed several very successful "best-seller" integrated circuits, many of them in continuous production for multiple decades. These include the LM331 voltage-to-frequency converter, and the LM337 adjustable negative voltage regulator.
NXP Semiconductors N.V. is a global semiconductor manufacturer headquartered in Eindhoven, Netherlands. The company employs approximately 31,000 people in more than 35 countries, including 11,200 engineers in 33 countries. NXP reported revenue of $9.4 billion in 2018.
The integrated circuit (IC) chip was invented during 1958–1959. The idea of integrating electronic circuits into a single device was born when the German physicist and engineer Werner Jacobi developed and patented the first known integrated transistor amplifier in 1949 and the British radio engineer Geoffrey Dummer proposed to integrate a variety of standard electronic components in a monolithic semiconductor crystal in 1952. A year later, Harwick Johnson filed a patent for a prototype IC. Between 1953 and 1957, Sidney Darlington and Yasuro Tarui proposed similar chip designs where several transistors could share a common active area, but there was no electrical isolation to separate them from each other.
