Abstract
An apparatus for performing capacitor amplification in an electronic device may include a first resistor and a second resistor that are connected in series and coupled between a set of input terminals of a receiver in the electronic device, a common mode capacitor having a first terminal coupled to a common mode terminal and having a second terminal, and an alternating current (AC)-coupled amplifier that is coupled between the common mode terminal and the second terminal of the common mode capacitor. The first resistor and the second resistor may be arranged for obtaining a common mode voltage at the common mode terminal between the first resistor and the second resistor. In addition, the common mode capacitor may be arranged for reducing a common mode return loss. Additionally, the AC-coupled amplifier may be arranged for performing capacitor amplification for the common mode capacitor.
