Abstract
A bootstrapped switch circuit includes a first switch transistor to receive an input signal and a second switch transistor to provide an output signal. The sources of the switch transistors may be coupled. A voltage source may be coupled to the sources of the switch transistors and at least one of the gates of the switch transistors. The voltage source may generate a control voltage to activate at least one of the switch transistors based on a bias current. A voltage source driver may be coupled to the voltage source to generate the bias current based on a bias voltage. The bias voltage may include a first voltage approximately corresponding to an overdrive voltage of at least one of the switch transistors and a second voltage approximately corresponding to a threshold voltage of the switch transistors.
