摘要:
A circuit for implementing a charge/discharge switch in an integrated circuit is described. The circuit comprises a supply bias path coupled to a first node, wherein the supply bias path provides a charging bias current to the first node; a charge transistor connected between the first node and a first terminal of a capacitor; a charge switch coupled between the first node and a ground potential, wherein the charge switch enables charging of the capacitor by way of the first node; a discharge transistor connected between the first terminal of the capacitor and a second node; a discharge switch coupled between the second node and a reference voltage, wherein the discharge switch enables discharging of the capacitor by way of the second node; and a ground bias path coupled between the second node and ground, wherein the ground bias path provides a discharging bias current to the second node. A method of implementing a charge/discharge switch in an integrated circuit is also described.
