Jul 4, 2022 · The prototype 5-way TI SAR ADC is fabricated in a 28 nm CMOS process and occupies a 0.03 mm2 area including on-chip calibration. With the ...
Abstract—This brief presents the on-chip background off- set and timing-skew calibration of the 1-then-2b/cycle time- interleaved ...
The proposed calibration sufficiently suppresses noise floor and spurs, and all calibrations are performed in the background without interfering with normal ADC ...
This paper presents a two-way time-interleaved (TI) 7-bit 2-GS/s successive-approximation-register (SAR) analog-to-digital converter (ADC) in 28 nm CMOS.
In this paper, we focus on the cutting-edge timing-skew calibration technique using a window detector.
