Abstract
A multistage noise shaping (CT-MASH) converter with phase alignment is provided. The CT-MASH converter may include a prefilter, an auxiliary path with an adjustable continuous time sigma delta converter (CTSD), and a modulator. The adjustable CTSD may provide phase alignment using one or more of a variety of techniques, such as modifying a group-delay of the CTSD by tuning a feedforward coefficient, by tuning an excess loop delay coefficient, and/or by adjusting a clock timing of the CTSD.
