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

Abstract: In this brief, we analyze two actively compensated amplifiers identified in a recently proposed negative impedance converter (NIC) regarding their phase and gain errors. We also study the ...

Abstract: In this paper, a single-stage and a two-stage high gain operational amplifiers (op-amp) developed in a 22nm fully depleted silicon on insulator (FDSOI) CMOS process are presented. High gain ...

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.

A short description of the lock-in technique gives an idea of the working principle of these useful devices, that are spreadly used in weak signals detection, but rarely treated in introductory ...
