Summary

Basic properties of active tripoles(BJT, JFET, MISFET). Description of basic modern op amps function blocks (differential input amplifier, current mirror as an active load, modern complementary follower)-their application in modern amplifier structures (voltage feedback amps - VFA, current feedback amps - CFA, transconductance amps - OTA, VFA based on CFA,current conveyors - CC, etc.) - their basic application circuits.

Way of continuous check of knowledge in the course of semester

Evaluation criteria are oriented on outputs allowing: • Reports from selected measurements processed on the base of measured values from these measurements and their subsequent processing, completing and assessing. • Continuous verifying of student knowledge in the numerical exercises in a form of debate and inquiries to achieve student active participations in study process. Identify, deduce and search of problem solving and their interpretation by students. • Tests and problems from numerical exercises, eventually from chosen theoretical circuits • Term work and projects on a given theme on the basis of selection, investigation, ordering and final compilation of facts and their processing into final form of given theme.
