Abstract
A track and hold circuit includes a signal input terminal, a clock input terminal, an output terminal, a transistor, and a bootstrapping circuit with a transformer. The transistor includes a source, a drain, and a gate, where the source is coupled to the signal input terminal, and the drain is coupled to the output terminal. The transformer includes a primary winding coupled to the clock input terminal, and a secondary winding. The secondary winding is coupled between the source and the gate to control a gate-source voltage of the transistor.
