Abstract
A gate drive circuit is disclosed that charges the gate of a switching transistor to a voltage that is high enough to turn the switching transistor fully on and then prevent the charge from flowing back into the gate drive circuit. The gate drive circuit works with a ground rectifier switch by providing a fully differential connection of the switching transistor and its capacitor and resistor in parallel with the antenna.
