Abstract
A measurement circuit for monitoring at least one parameter of an input signal received from an external signal source includes at least one first measurement element coupled to the input signal and configured to provide an initial measurement signal indicative of a respective one or more of the at least one parameter of the input signal. An analog to digital converter is coupled to receive a signal indicative of the analog output signal and a reference voltage and configured to generate a digital output signal representative of the analog output signal. A compensation circuit is responsive to an output of at least one second measurement element and to a reference signal to generate a compensation signal indicative of a difference between the output of the at least one second measurement element and the reference signal. A voltage level of the reference voltage is adjusted in response to the compensation signal.
