Abstract

A novel current-mode biquad using only operational amplifiers (OAs) and multiple current output operational transconductance amplifiers (OTAs) is introduced. The proposed circuit can realise five different biquad transfer functions simultaneously. This circuit enables the circuit characteristics to be electronically tuned. An example is given, together with simulated results by PSPICE.
