Abstract
An analog-to-digital converter (ADC) can include a continuous-time delta sigma modulator and calibration logic. The calibration logic can calibrate direct feedback and flash clock delay coefficients of the continuous-time delta-sigma modulator without interrupting the normal operations of the ADC (e.g., in situ). Thus, the calibration logic can rectify performance and stability degradation by calibrating suboptimal coefficients.
