Abstract
A new CMOS realization of the differential difference amplifier (DDA) circuit is proposed. The DDA circuit is realized using a wide input ra nge differential difference transconductor (DDT) and a complementary f olded cascode (CFC) gain stage. The DDA circuit is used to realize a M OS-C oscillator suitable for VLSI with a simple circuit to control the amplitude of oscillation. PSpice simulation results for the proposed DDA circuit and the DDA based MOS-C oscillator are also given.
