Abstract
This disclosure relates to auto-averaging RC time constant calibration are described. An auto-averaging calibration circuit includes two capacitor branches, where capacitors in the capacitor branches, charge and discharge alternately to accommodate multiple charging cycles in one measurement cycle for measuring a RC time constant. A value of RC time constant is obtained in each charging cycle. A final value of the RC time constant can be determined by averaging various values of the time constants obtained during each charging cycle.
