A circuit for implementing a charge/discharge switch in an integrated circuit is described. The circuit comprises a supply bias path (203) coupled to a first node (204), wherein the supply bias path provides a charging bias current to the first node; a charge transistor (206) connected between the first node and a first terminal (212) of a capacitor (202); a charge switch (250) coupled between the first node and a ground potential (GND), wherein the charge switch enables charging of the capacitor by way of the first node; a discharge transistor (231 ) connected between the first terminal of the capacitor and a second node; a discharge switch (270) coupled between the second node (236) and a reference voltage, wherein the discharge switch enables discharging of the capacitor by way of the second node; and a ground bias path (232) coupled between the second node and ground, wherein the ground bias path provides a discharging bias current to the second node.
