Pulse-width modulation in sigma-delta modulators


Time-encoding machines map analog or multi-bit digital signals to a binary stream. The information contained in the input signal is preserved by the high resolution achieved in the time domain. Pulse-Width Modulators (PWMs) rely on a similar operation principle. This paper explores two applications of PWMs to the design of data converters based on Sigma… (More)
