General Instrument (GI) was an American electronics manufacturer based in Horsham, Pennsylvania, specializing in semiconductors and cable television equipment. They formed in New York City in 1923 as an electronics manufacturer.
The building at 844 East Charleston Road, Palo Alto, California, where the first commercially practical integrated circuit was invented. In 1955, William Shockley founded Shockley Semiconductor Laboratory, funded by Beckman Instruments in Mountain View, California; [6] his plan was to develop a new type of "4-layer diode" that would work faster and have more uses than then-current transistors.
Renesas Electronics started operation in April 2010, through the integration of NEC Electronics, established in November 2002 as a spin-off of the semiconductor operations of NEC with the exception of the DRAM business, [8] [9] and Renesas Technology established on April 1, 2003, the non-DRAM chip joint venture of Hitachi and Mitsubishi, with their ownership percentage of 55 and 45 in order.

As the law is logarithmic, the percentage loss of capacitance will twice between 1 h and 100 h and 3 times between 1 h and 1,000 h and so on. Aging is fastest near the beginning, and the absolute capacitance value stabilizes over time. The rate of aging of Class 2 ceramic capacitors depends mainly on its materials.
The company was founded by two MIT graduates, Ray Stata and Matthew Lorber in 1965. [9] The same year, the company released its first product, the model 101 op amp, [10] which was a hockey-puck sized module used in test and measurement equipment. [11]
