dc.description.abstractThis paper proposes the application of an electronically controlled current-mode for a level shifted multicarrier PWM generator. The proposed circuit consists of two multiple-output current follower transconductance amplifiers (MO-CFTAs) for the multiple-output triangular generator and four current follower transconductance amplifiers (CFTAs) for the signal comparator. The characteristics of the circuit are as follows: the current output can be controlled by bias current, the maximum amplitude deviation due to temperature variation is less than 1.37% and the power consumption is approximately 0.744 microwatt, at ±1.5V supply voltages. The proposed PWM has been verified through PSpice simulation results which are in consistent with the theoretical analysis.en
