Abstract

This paper proposes a PWM circuit using CMOS OTAs. The features of the proposed PWM circuit are IC oriented circuits, simple configuration, and bias current controlled output. In order to verily the validity of the proposed circuit, it is simulated by H-SPICE program. Futhermore, the proposed circuit is integrated on chip using 0.35 $\mu\textrm{m}$ CMOS technology.
