Differential all-pass coupling circuit with common-mode feedback

The invention discloses a differential all-pass coupling circuit with common-mode feedback. The invention discloses a differential all-pass coupling circuit with common-mode feedback. An example apparatus includes an anti-aliasing circuit configured to reduce a bandwidth of a first differential signal; and a switched capacitor circuit coupled to the anti-aliasing circuit configured to control the first switch based on a first difference between (i) a common mode input voltage associated with a first common mode voltage of the first differential signal and (ii) a common mode reference voltage associated with a second common mode voltage of the input stage of the receiver, the controller controls the first switch to charge the capacitor to a first voltage, controls the second switch to provide a second voltage to the capacitor based on a second difference between the first differential signal and the common mode input voltage, and outputs a second differential signal to the input stage based on the first differ
