Abstract
A voltage sampling circuit and method are provided. The voltage sampling circuit includes a capacitor having a first terminal and a second terminal. A first pre-charge circuit is coupled to a first voltage supply terminal and to the first terminal of the capacitor. The first pre-charge circuit is configured to receive a first control signal and pre-charge the capacitor to a first voltage. A switch circuit includes a first transistor having a first current electrode coupled to an input terminal of the voltage sampling circuit, a control electrode coupled to the first terminal of the capacitor, and a body electrode coupled to the second terminal of the capacitor. A second transistor having a first current electrode coupled to a second current electrode of the first transistor, a body electrode coupled to the second terminal of the capacitor, and a second current electrode coupled to an output terminal of the voltage sampling circuit.
