Abstract
A PWM Circuit using CMOS OTA is proposed. It features that the oscillation frequency is independent of supply voltage and temperature, and is linearly controlled by the bias current of OTA. The H-SPICE simulation results are given and they show good performance of the proposed circuit. The layout results using 0.3${\mu}{\textrm}{m}$ CMOS technology for IC implementation are also given.
