This paper presents a foreground calibration technique with LSB capacitors for an 18-bit SAR ADC. Calibration using LSB capacitors suffers from poor accuracy owing to the comparator static offset and ...

This paper presents a 5-bit 1.25-GS/s folding flash ADC. The prototype achieves a folding factor of four with a capacitive folding technique that only consumes dynamic power. Incorporated with various ...
