Abstract

In recent years Operational Transconductance Amplifier (OTA) based integrated circuits, filters and analog circuits have been widely investigated. The usefulness of OTAs over conventional OP-Amps in the design of active circuits are well documented. This paper presents a new sinusoidal frequency-to-voltage converter which can linearly convert low voltage signals which is not possible with commercial converter ICs such as LM2917. This converter is based on an OTA based differentiator and an OTA based half wave rectifier.
