Abstract
A pipelined SAR ADC includes a first stage and passive residue transfer is used to boost a conversion speed. Owing to the passive residue transfer, the first stage may be released during a residue amplification phase, cutting down a large part of the first-stage timing budget. An asynchronous timing scheme may also be adopted in both the first- and second-stage SAR ADCs to maximize the overall conversion speed. Lastly, a dynamic amplifier with proposed PVT stabilization technique may be employed to further save power consumption and improve the conversion speed simultaneously.
