Abstract
A pulse generator. The pulse generator has a pseudo random number generator, a comparator coupled to the pseudo random number generator, and a register coupled comparator. The comparator performs comparisons of values generated by the pseudo random number generator and a value in the register, wherein the comparator outputs a pulse that is modulated according to the comparison. A low-pass filter may coupled to the comparator output and the register may receive samples of a digital signal. Low-pass filtering the comparator output implements a digital-to-analog converter that is less expensive than conventional delta-sigma modulator DACs and has better performance than conventional PWM DACs.
