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, etc.). Basic application circuits and notes. Degradation of semiconductor structures.

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.

Lectures: Voltage feedback amplifier as an ideal element; basic feedback concept. Tubes, bipolar and unipolar transistors - history, basic properties. Differential transistor input stage; follower (modern - complementary); current source as active load; current mirror. Voltage feedback amplifiers - VFA - with limited current source in the input stage (classical). Basic VFA applications (amplifiers, generators, comparators). Current feedback amplifiers - CFA. Basic CFA applications. VFA based on CFA structure. Typical nonlinear applications of operational amplifiers. Operational transconductance amplifier (OTA) principle, Northon amplifier (NA) principle, current conveyor (CC) principle. Comparision of op amps structures from point of view of application properties. Principle of regulated sources, band - gap reference. 1. and 2. order filters, principle of cascade filters. Degradation of electronic elements with temperature, dissipated power (causes of degradation) - reduction of influence (abduction of heat - heat sink). Exercises: Basic transistor amplifiers; quiscent point. Amplifiers with ideal OPA (invert, noninvert, differential). Comparators, generators and oscillators -ideal OPA. Influence of real OPA properties. An example of nonlinear application -rectifier, limitter. 1. and 2. order filters, principle of cascade filters. Definition of project, discussion. Laboratories: Measuring of inverting and noninverting amplifier properties - data sheets. Measuring of differential amplifier properties - data sheets. Measuring of degradation of amplifier frequency properties with gain increasing. Measuring of properties of square wave generator - data sheets. Measuring of rectifiers and limiters.
