The operational amplifier is one of the basic building blocks in analog designs. There are several commercial operational amplifiers already available in the market. The commercial electronics have an operating temperature range from -40AdC to 85AdC. Lunar atmospheres have a temperature range of -180AdC to 120AdC. This operational amplifier was designed for lunar applications and is a part of a NASA project for lunar unmanned missions.1[1] Ge , p-Si Emitter Base Collector Figure 2.1.1 Energy band diagram of graded base SiGe HBT In a conventional Si BJT device, the minority charge carriers are injected into the base region then diffuse into the collector region due to theanbsp;...
