From: mniederb@pws2.itr.ch (Niederberger Markus) Subject: Characterization of opamps Organization: Interkantonales Technikum Rapperswil (ITR) Switzerland Lines: 23 Hi, Right now I should do some characterization of opamps. Because I don't have special equipment for this task, I have to do this job with relativly simple equipments (Frequency sweeper, DSO, etc.). Does anyone know good test circuitry for characterization of opamps? Especially for measuring open-loop gain, phase margin, PSSR, CMMR and so on. Are there any books or application notes on this subject available? Please reply vi e-mail or nn.
