Abstract
A new circuit structure which improves performance of a pulse width modulator is proposed in this paper. The proposed PWM circuit is based on a phase locked loop (PLL) system where the input signal is fed to combine with the output of a phase detector (PD). which it achieve a high accuracy PWM output. In addition, we also use R-S flip-flop and monostable circuit as a phase detector which give rise to get a PWM modulator that wide input range. The experimental result agree well with an analytical result. © 2008 IEEE.
