Abstract
A bootstrapped switch circuit is disclosed. The bootstrapped switch circuit includes a sample transistor having a source coupled to an input terminal and a drain coupled to an output terminal. The bootstrapped switch circuit further includes a charge path to charge a bootstrap capacitor during a hold phase and a bootstrap path configured to apply a voltage of the bootstrap capacitor to the gate of the sample transistor during a sample phase. The bootstrap path includes a low-side transistor configured to couple a first terminal of the bootstrap capacitor to the source of the sample transistor during the sample phase, and a high-side transistor configured to couple a second terminal of the bootstrap capacitor to the gate of the sample transistor during the sample phase. The bootstrapped switch circuit further includes a bootstrap transistor bootstrap transistor configured to maintain an on-state of the high-side transistor during the sample phase.
