Silicon die of the first 555 chip (1971) Die of a CMOS NXP ICM7555 chip. The timer IC was designed in 1971 by Hans Camenzind under contract to Signetics. [3] In 1968, he was hired by Signetics to develop a phase-locked loop (PLL) IC. He designed an oscillator for PLLs such that the frequency did not depend on the power supply voltage or ...
Chip-on-glass (COG), a variation of COB, where a chip, typically a liquid crystal display (LCD) controller, is mounted directly on glass. Chip-on-wire (COW), a variation of COB, where a chip, typically a LED or RFID chip, is mounted directly on wire, thus making it a very thin and flexible wire.
Hans R. Camenzind (Swiss Standard German: [ˈkaːməntsɪnd]; 1 January 1934 – 8 August 2012 [1]) was an electronics engineer known for designing the 555 timer IC in 1971 under contract to Signetics. [2] He was the inventor on 20 US patents.
The Signetics 2513 [5] [6] was a character generator chip used in the TV Typewriter, [7] Apple I, and early versions of the Apple II, as well as Atari's earliest arcade games. The Signetics 82S100 FPLA (Field Programmable Logic Array) was the first commercially successful user programmable logic device , the forerunner of the modern FPGA .

English: The NE555 contains 24 bipolar transistors, two diodes and 15 resistors that form six functional blocks: Between the supply voltage VCC (+) and the ground GND (-) is a voltage divider consisting of three identical resistors which, when connected not from the outside, the two reference voltages ¹ / 3 VCC and ² / 3 VCC supplies.
The following is a list of CMOS 4000-series digital logic integrated circuits.In 1968, the original 4000-series was introduced by RCA.Although more recent parts are considerably faster, the 4000 devices operate over a wide power supply range (3V to 18V recommended range for "B" series) and are well suited to unregulated battery powered applications and interfacing with sensitive analogue ...
Besides the commercial vendors there are plenty of free GDSII utilities. These free tools include editors, [3] [4] [5] viewers, [6] utilities to convert the 2D layout data into common 3D formats, [7] [8] utilities to fly through a 3D version, [9] utilities to convert the binary format to a human readable ASCII format [10] and program libraries ...
