An Analog On-Chip Adaptive Body Bias Calibration for Reducing Mismatches in Transistor Pairs

Device parameter variations exhibit an increasingly serious impact on analog and mixed-signal circuit behavior. In this paper, we propose a novel fully-analog on-chip adaptive body bias calibration method, for efficiently reducing mismatches in transistor pairs. We present three circuit implementations which achieve a mismatch reduction between 61% and 73% in terms of standard deviation.
