Abstract :
In recent years Operational Transconductance Amplifier based high frequency integrated circuits, filters and systems have been widely investigated. The usefulness of OTAs over conventional OP-Amps in the design of both first order and second order active filters are well documented. This paper proposes two first order voltage controlled all pass filters with phase tuning capability. Simulation results are obtained in TINA® and verified by experimental results.
