BEYOND-THE-RAILS BOOTSTRAPPED SAMPLING SWITCH

A bootstrapped switch circuit may include a signal switch configured to, when enabled via a gate terminal of the signal switch during a sampling phase of the bootstrapped switch circuit, pass an input signal received at its input to its output. The bootstrapped switch circuit may also include a bootstrap circuit coupled to the signal switch comprising a bootstrap capacitor and a plurality of switches coupled to the bootstrap capacitor, wherein one of the plurality of switches comprises a p-type field effect transistor configured to decouple, by deactivating a second p-type field effect transistor, the bootstrap capacitor during a bootstrap phase of the bootstrapped switch circuit in which the signal switch is disabled, and further wherein the p-type field effect transistor is coupled to other of the plurality of switches and the bootstrap capacitor such that the signal switch is able to pass the input signal having a magnitude greater than voltage supply rails of the bootstrapped switch circuit from the input to the output.
