An anti-log amplifier design with a temperature-compensation network built around a nearly linear PTC thermistor.

Abstract: Switched capacitor common-mode feedback (SC-CMFB) is a popular technique for stabilization of the output common-mode level of fully differential operational amplifiers. It provides ...

Abstract: In this paper, an “architectural” description of an instrumentation amplifier (in-amp) is used to simulate its common mode rejection ratio (CMRR) and voltage offset (VOS) in high temperature ...
