Wide-Temperature-Range Integrated Operational Amplifier

A document discusses a silicon-oninsulator (SOI) complementary metal oxide/ semiconductor (CMOS) integrated- circuit operational amplifier to be replicated and incorporated into sensor and actuator systems of Mars- explorer robots. This amplifier is designed to function at a supply potential ≤5.5 V, at any temperature from –180 to +120 °C. The design is implemented on a commercial radiationhard SOI CMOS process rated for a supply potential of ≤3.6 V and temperatures from –55 to +110 °C. The design incorporates several innovations to achieve this, the main ones being the following:
