Abstract: An interleaved analog to digital converter (“ADC”) includes a first ADC having an input for sampling an analog signal during a first time period, an output for providing a digital signal, and a power supply terminal for receiving a first power supply voltage, a second ADC having an input for sampling the analog signal during a second time period, an output for providing a digital signal, and a power supply terminal for receiving a second power supply voltage, a first skew estimator for estimating a skew value of the first ADC, a second skew estimator for estimating a skew value of the second ADC, and a comparator for comparing the skew values, adjusting the first power supply voltage in response to a first output value of the comparator, and adjusting the second power supply voltage in response to a second output value of the comparator.
