A 12b 180MS/s Pipelined-SAR ADC with a Low-Power Calibration-Free RA and Hardware-Efficient SAR Logic

A 12b 180MS/s Pipelined-SAR ADC with a Low-Power Calibration-Free RA and Hardware-Efficient SAR Logic 150 150

Abstract:

This letter presents a 12-bit 180-MS/s pipelined-SAR ADC in 65-nm CMOS. To eliminate the complex interstage gain-error calibration for fast-response characteristic, a high-gain residue amplifier (RA) featuring a 2-stage gain-boosting architecture is proposed. By removing the tail current, the RA significantly alleviates slew-rate and voltage headroom limitations. The pre-amplifier …

Minimizing the Noise in Low-Current Sensing by MOSFET p-n Junction Diode Feedback

Minimizing the Noise in Low-Current Sensing by MOSFET p-n Junction Diode Feedback 150 150

Abstract:

This letter proposes a transimpedance amplifier (TIA) architecture that minimizes noise for continuous-time (CT) low-current sensing. The approach leverages a MOSFET to realize a pure p-n junction diode as the TIA feedback element, such that MOS channel conduction is completely suppressed. Therefore, channel-induced noise contributions associated with conventional MOS-based feedback …
