Open publisher page 51 citations

Abstract

This paper introduces a voltage-mode biquad using only active devices such as operational amplifiers (OAs) and operational transconductance amplifiers (OTAs). The proposed circuit can realize five different biquad transfer functions by choosing the input and output terminals. Also the circuit characteristics can be electronically tuned by adjusting the transconductance gains of the OTAs. An example is given, together with simulated results by PSPICE. The circuit configuration is very suitable for implementation in both bipolar and CMOS technologies.
