Abstract:
1. A method for processing an electronic signal, the method comprising: removing at least a portion of a DC offset from outputs of an amplifier based on: first differential signals generated by a first circuit based on said outputs of said amplifier, said first circuit having a variable corner frequency; second differential signals generated by a second circuit based on said first differential signals; and selectively enabling communication of said first differential signals to enable generation of said second differential signals, wherein said second differential signals are selectively communicated to differential inputs of said amplifier, wherein said first circuit and said second circuit are part of a DC offset correction circuit, wherein said second differential signals represent an output of the DC offset correction circuit, wherein a positive output of said second circuit is coupled to a positive input of said amplifier, and wherein a negative output of said second circuit is coupled to a negative input of said amplifier.
