摘要

Exemplary implementations of electrical circuits and systems are disclosed, and methods for signal processing including sampling and quantizing of amplitude and band limited signals implemented through a Passive Pulse Modulation Analog to Digital Converter (PMADC).

主权项

1. An Analog to Digital Converter (ADC) electrical circuit including an analog modulator, the analog modulator comprising:
a passive continuous time filter to: receive an analog signal, to receive a feedback signal, and to provide an output signal; and an asynchronous comparator configured to receive the output signal, the comparator further configured to vary a timing property of an output signal of the comparator based on a magnitude of the analog signal received by the passive continuous time filter.
