This manual is aimed at the study of the mode of operation of the circuits of the integrator and differentiator based on an operational amplifier by simulating the modes using the software package Micro-Cap and consolidate the theoretical material in the section "Analog circuit design". These manual contains the description of integrator and differentiator working principles and configuration methods of elimination the output voltage effects of drift due to the excitation of operational amplifier underlying operating scheme.
Qucs open-source circuit simulator and its applications for educational and research applications in field of EMC and ESD are considered. Its advantages and disadvantages are considered. New features introduced in Qucs are considered. One of the authors is Qucs developer.
