Subject aims expressed by acquired skills and competences

After completing this course, the student should be able to analyze and construct linear circuits (amplifiers, filters, oscillators) with real active circuit elements: operational amplifier; transconductance amplifier; transimpedance amplifier; current conveyor

Teaching methods

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

Verification of study: tests laboratoriesproject Conditions for credit: Student must work out three tests. Student can receive up to 6 points for each of tests. Maximum number of points student can gain through tests is 3 * 6 = 18 points. Student can gain up to 6*2= 12 points from the laboratories.Student can gain up to 14 points from the project. To pass the excercises part of course student has to gain at least 26 points. Student can gain up to 56 points from the final exam (circuit work - 32 points, oral part - 24 points). To pass the course student has to gain at least 51 points.
