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

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 ...

Download the PDF of this blog, where Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20.

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 ...
