Abstract

An analog multiplier-divider circuit that realized through the use of OTAs, which does not require external passive circuit elements and temperature compensated, is proposed in this paper. Since the scheme is realized in such a way that employs only OTA as a standard cell, the circuit is simple and can be easily constructed from commercially available IC. The circuit bandwidth is wide and close to the transistor f$\sub$T/. Simulation results that demonstrate the performances of the multiplier-divider circuit are included.
