Abstract
A simple pulse width modulator (PWM) is proposed. The circuit principle is based on a relaxation oscillator with a second generation current conveyor (CCII). The proposed scheme is simpler than the existing PWM methods and the duty factor linearly depends on the modulating signal. Another advantage is that the circuit is suitable for IC implementation. The simulation and experimental results are given. They show good agreement with the theoretical analysis
