Receiver systems and methods for AC and DC coupling of receiver

Abstract

An Alternating Current (AC) and Direct Current (DC) coupled electronic receiver system including a receiver, an AC-coupling capacitor between an input of the receiver system and the receiver, a bypass switch configured to selectively bypass the AC-coupling capacitor to DC-couple the input to the receiver, a bypass switch driving circuit configured to cause the bypass switch to switch ‘ON’ and thereby DC-couple the input to the receiver, and cause the bypass switch to switch ‘OFF’ and thereby AC-couple the input to the receiver, and a voltage-following transistor between a source and a gate of the bypass switch configured to maintain an ‘OFF’ state of the bypass switch while the input is AC-coupled.
