Abstract

A CMOS realization of the current-feedback differential difference amplifier (CFDDA) is proposed. The CFDDA circuit is realized using a wide input range dependent load transconductor (DTA) with three independent input voltages and a rail to rail class-AB voltage buffer. The CFDDA circuit is used to realize a MOS-C oscillator suitable for VLSI. PSpice simulation results for the CFDDA circuit and for its based MOS-C oscillator are also given
