Abstract
A bootstrapped switch circuit includes an auxiliary loop circuit for assisting the boosting of a bootstrap voltage in a main loop circuit having a bootstrapped switch transistor. The boosted bootstrap voltage switches on the bootstrapped switch transistor so that an input voltage signal may conduct through the bootstrapped switch transistor to charge a sampling node.
