Systems are disclosed 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, comprising a switchable high pass filter configured to receive a signal, the switchable high pass filter including a plurality of high pass filters connected in parallel, wherein at least one of the plurality of high pass filters has a tunable corner frequency.
