Abstract
This paper introduces a way to realize high-pass, band-stop and all-pass transfer functions using Operational Transconductance Amplifiers (OTAs) and grounded capacitors. The basic circuit configuration is constructed with five OTAs and two grounded capacitors. In the circuit with the proportional block, it is shown that the circuit parameters can be independently set and electronically tuned by the transconductance gains. Although the circuit configuration has been Down, it seems that the feature for realizing the high-pass, the band-pass and the all-pass transfer functions makes the structure more attractive and useful. An example is given together with simulated results by PSPICE.
