Abstract
In converting a staircase waveform signal into a smoothed analog signal, this circuit can perform the high-quality conversion without any sophisticated lowpass filter. An input staircase signal is delayed for one stepping interval to produce a differential signal which represents a stepping height at each step, by taking the difference between the input staircase signal and the one stepping interval delayed version thereof. The differential signal is integrated at every stepping interval. The integrated voltage forms a sawtooth wave signal which is in turn additively combined with the one stepping interval delayed version of the input staircase signal. The resulted combined signal is a smoothed signal of the input staircase signal.
