Active filters and oscillators using current feedback operational amplifiers.

摘要

In this thesis, New current feedback operational amplifier (CFOA)-based filter, oscillator and signal generator circuits were proposed. In order to be compatible with integration requirements, these circuits use minimum number of active elements and enjoy independent control of the critical circuit parameters. The effects of parasitics, voltage and current tracking errors of the CFOA on the circuit parameters were discussed. Reasonable agrement between theory and measurements was obtained in all circuits.
