ABSTRACT:
A circuit for providing a periodic output having a regulated magnitude is derived from a periodic input source. A switch is serially connected to the input for periodically sampling the input at a sampling frequency which is much higher than the frequency of the periodic input, while the duty ratio of the sampling is modulated as an inverse function of the output magnitude. The pulse train of samples is filtered to remove the sampling frequency and its harmonics and the result is a regulated output which replicates the input waveform.
