摘要

An optimized calibration methodology for high-speed comparators is proposed. The key features of this methodology are the offset extraction technique and the body-biasing calibration. The offset extraction technique uses a fast and accurate smart resettable successive approximation register (SR-SAR) algorithm to calculate the offset voltage (Vos). The body-biasing calibration is a simple iterative...
