High input impedance voltage-mode multifunction filters using plus-type CCIIs

摘要

A new configuration for realising high input impedance voltage mode filters using only plus-type current conveyors (CCII+) is presented. This configuration uses only grounded resistors and capacitors and can simultaneously realise lowpass, bandpass and highpass responses. The use of only plus-type CCIIs simplifies the configuration. PSPICE simulation results are also included.
