Patent ID: 8547157

Claim:
A circuit comprising: a radio frequency (RF) switching device having a gate terminal, the RF switching device configured to receive an RF input signal and to pass an RF output signal if the RF switching device is activated; a gate resistor coupled between the gate terminal and a control terminal, the control terminal configured to receive a control signal to activate the RF switching device; and a helper circuit coupled in parallel with the gate resistor, the helper circuit configured to provide a temporary conductive path between the control terminal and the gate terminal in response to a state transition of the control signal, wherein the helper circuit includes: a helper switching device coupled in parallel with the gate resistor, the helper switching device having a helper gate terminal; a coupling capacitor coupled between the helper gate terminal and the control terminal to turn on the helper switching device in response to the state transition of the control signal; and a discharge resistor coupled between the helper gate terminal and the gate terminal of the RF switching device to turn off the helper switching device when a voltage at the gate terminal is equal to a voltage at the control terminal.
