Abstract:
Low noise charge pumps are disclosed. In certain embodiments, a charge pump includes a charge pump output terminal configured to provide a charge pump voltage, a switched capacitor, an inverter having an output electrically connected to a first end of the switched capacitor, a pair of charging switches connected between a second end of the switched capacitor and a reference voltage, and a pair of discharging switches connected between the second end of the switched capacitor and the charge pump output terminal. The pair of charging switches is closed during a charging operation and open during a discharging operation, while the pair of discharging switches closed during the discharging operation and open during the charging operation.
