| 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.
