A method and system of establishing an offset for a receiver. In one embodiment, a method includes receiving an input signal and generating a first signal. The method can further include integrating the input signal and the first signal at a reference node. In addition, the method can include comparing the input signal to a signal at the reference node and generating an output signal, analyzing the output signal to determine whether the output signal contains noise, and modifying the first signal based on the analysis of the output signal.
