Abstract
Results are presented of an analog LSI CMOS missile autopilot. The autopilot is a two-chip set which requires a total area of 210000 sq miles and consumes 700 mW of power. The set is fabricated in a double-poly p-well silicon-gate technology. The chips perform a wide array of analog functions, including precision filtering, full-wave demodulation, digital-to-analog conversion, limiting, pulsewidth modulation, and offset cancellation. A number of digital functions are also provided. The chip set was functionally correct on the first iteration after computer-aided verification. The output noise of the chip set is 6.5 mV, integrated over a bandwidth of 5-500 Hz. Results are presented over a temperature range of -55/spl deg/C to 125/spl deg/C.
