More Information
Summary:Charging and discharging circuits for assisting charge pumps are disclosed. In certain embodiments, a radio frequency (RF) switch system includes an RF switch that receives an RF signal and is controlled by a switch control signal received at an input, a first charge pump configured to generate a first charge pump voltage, a level shifter powered by the first charge pump voltage and that generates the switch control signal based on a switch enable signal, and a charge pump assistance switch coupled to the input of the radio frequency switch and that activates to assist the first charge pump in response to a transition of the switch enable signal from a first state to a second state.
