A 12-bit 210-MS/s 2-Times Interleaved Pipelined-SAR ADC With a Passive Residue Transfer Technique.

A 12-bit 210-MS/s 2-channel time-interleaved analog-to-digital converter (ADC) employing a pipelined-SAR architecture for low-power and high-speed application is presented. The proposed ADC is partitioned into 3 stages with a passive residue transfer technique between the 1st and 2nd stages for power saving and active residue amplification between the 2nd and 3rd stages for noise consideration.
