Abstract
An analog to digital convertor (ADC) comprises an integrator having an input selectively connected to an intermediate frequency (IF) signal input and an output connected to a summer. The summer has an output connected to an input of a quantizer, the quantizer output being operatively connected to a signal strength indicator. The integrator includes a programmable gain feedback component. The summer has a synthesized calibration signal input, the value of the programmable gain feedback component being configured to vary when a synthesized calibration signal at the intermediate frequency is applied to the summer. The signal strength indicator is configured to detect a value of the programmable gain feedback component when the signal strength is minimized and to calibrate the ADC accordingly.
