Methods and systems that utilize AC-coupled filtering to reduce DC offset, with aspects dynamically correcting instantaneous DC offset generated from the AC-coupled filtering. A DC offset correction circuit for an radio frequency (rf) receiver comprises a switchable high pass filter receiving a downconverted rf signal. The switchable high pass filter has N selectable corner frequencies, where N is greater than two.
