Abstract
Radio frequency switches with improved switching speed are provided. In certain embodiments, an RF switching circuit includes a FET switch including a gate, a digital buffer configured to provide a first output voltage to the gate of the FET during a steady-state, and a fast switching circuit in parallel with the digital buffer and configured to provide a second output voltage to the gate of the FET during a switching state. The fast switching circuit includes at least one charge pump configured to boost at least one supply voltage to a multiple of the at least one supply voltage. The fast switching circuit is configured to generate the second output voltage based on the boosted at least one supply voltage.
