Abstract :Pulse-Width Modulated Digital-Analog Converter insert ignore into journalissuearticles values(PWM DAC); is the most popular digital-analog conversion structure in embedded system design. However, there is no explicit formulation existing in the literature for the efficient utilization of PWM DAC implementation regarding to resolution and switching noise considerations. In this paper, PWM frequency selection formulization is given to limit switching noise less than least significant bit in the implemented DAC structure. In addition, to extend the limits of the PWM modulator, a hybrid R-2R and PWM structure is proposed for the resolution improvement, resulting as higher dynamic range for the total system.
Keywords : PWM DAC, pulse width modulation, R 2R DAC
