Interleaving is a powerful technique that boosts the speed of an ADC. The power efficiency of such a technique is mainly affected by the overhead of the circuitry used to mitigate the impact of inter-channel mismatches on the ADC’s performance. Thi

A capacitive DAC is an important building block of a charge-redistribution SAR ADC, for its size has a significant impact on performance. For medium- to high-resolution applications, the size of the DAC is typically determined by random mismatches. A

Dickson charge-pump (CP) is proposed here to realize a voltage-to-time converter (VTC) within an array of time-domain comparators of a 54-level time-mode subthreshold flash ADC operating at 0.36V. Two identical CPs in each of the 54 ADC slices conver

In this paper, we introduce a new switched-capacitor (SC) passive delta-sigma ( $\Delta \Sigma $ ) modulator architecture. It is based on a charge-sharing rotation technique, which eliminates any inter-stage loading effects that plague the convention
