Linear Integrated Systems is an American full-service designer and manufacturer of small-signal, discrete semiconductors and ultra-low-noise, monolithic dual and single JFETs and bipolar transistors, along with high-speed DMOS switches, small-signal MOSFETs, ultra-low leakage diodes and BiFET amplifiers and was founded in 1987 by Silicon Valley pioneer Timothy S. McCune in Fremont, California.
Linear Integrated Systems, Inc. (LIS) is an American full-service designer and manufacturer of small-signal, discrete semiconductors. LIS was founded in 1987 by Silicon Valley pioneer John H. Hall after his departure from Micro Power Systems. Fremont, California, United States In 2006, LIS announced the release of the LSK389 ultra-low-noise dual JFET. By the 2000s, LIS had moved away from custom IC work to focus on small-signal, discrete components for use in the test/measurement, medical, high-end audio and sensor applications. The metaloxidesemiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET), also known as the metaloxidesilicon transistor (MOS transistor, or MOS), is a type of insulated-gate field-effect transistor that is fabricated by the controlled oxidation of a semiconductor, typically silicon. The company produces over 2,000 different discrete semiconductors, including dual and single junction field effect transistors (JFETs), bipolar transistors, BiFETs, lateral DMOS analog switch and switch arrays, and picoamp dual and single diodes.
