Method for pipelining analog-to-digital conversion and a pipelining analog-to-digital converter with successive approximation

摘要

A method for pipelining an analog-to-digital conversion of an analog input signal into an N-bit digital output signal is disclosed where a multiplexer is used for the selection of pre-processed digital approximation values from a plurality of adders and subtractors. The selection is set after the decoding of the selected digital approximation values. Thus, considerable more time of the total iteration cycle is available for the pre-amplifier to settle at very high operation frequencies.
