Using Analog CMOS Arrays to Create Current Sources

9.1 RCA pioneered CMOS

Once the first stable MOSFETs had been created in the early 1960s by RCA

researchers Steve Hofstein and Fred Heiman, and by Dr. Frank Wanlass at Fairchild

Semiconductor, it opened the door to researching and developing other types of MOS

transistors. This included small-signal

complementary-MOS

(CMOS) devices, which

would theoretically have both N-channel and P-channel transistors coexisting on the

same chip together. Although other researchers around the world had tried, no one

had yet succeeded in doing this. It was an uncharted area, considered by many to be ...
