Abstract
A digital to analog converter includes a time encoder that converts an analog input signal into a asynchronous pulse sequence, a pulse asynchronous DeMUX circuit that converts the asynchronous pulse sequence into a parallel stream of pulse sequences at a relatively lower speed, a parallel pulse to asynchronous digital converter, an asynchronous digital to synchronous digital converter, a timing reference circuit to generate absolute time references, and a Digital Signal Processor. This architecture provides for analog to digital conversion based on pulse encoding with a parallel digitization scheme of the pulse encoded signal.
