Abstract
An ADC that may include a sampler that generates a series of current pulses; a group of charge memory units; a de-multiplexor for providing charge packets that reflect the series of current pulses to the group; at least one controller that causes different charge memory units of the group to receive charge packets from different current pulses during reception periods that start and end at points of tome outside the current pulses, a group of PWM modulators that are configured to generate PWM pulses that represent the charge packets stored by the group of charge memory units; and a processor that is configured to generate an output digital signal that represents the input analog signal based on the PWM pulses.
