Classification: CPC H | IPC H

Claim 9:
10. A radio frequency (RF) switching circuit comprising:
a field-effect transistor (FET) switch including a gate;
a digital buffer configured to provide a first output voltage to the gate of the FET switch during a steady-state of the FET switch, the first output voltage comprising at least one supply voltage; and
a fast switching circuit configured to provide a second output voltage to the gate of the FET switch during a switching state of the FET switch, the fast switching circuit comprising at least one charge pump configured to generate at least one boosted supply voltage by boosting the at least one supply voltage, the fast switching circuit configured to generate the second output voltage based on the at least one boosted supply voltage, the steady-state of the FET switch following the switching state of the FET switch,
wherein the at least one charge pump comprises a first charge pump including a first switch coupled between a power low supply voltage and a first node and configured to receive a precharge control signal, a second switch coupled between a power high supply voltage and the first node and configured to receive a discharge control signal, and a capacitor coupled between the first node and a second node.
