Abstract
An input circuit for an analog-to-digital converter (ADC) includes at least one bootstrap circuit, including at least one first switch for connecting electrical power to a first terminal of at least one capacitor; at least one second switch for connecting a second terminal of the at least one capacitor to a signal to be sampled; at least one third switch for connecting the first terminal of the at least one capacitor to the control gate of at least one sampling network input switch; at least one fourth switch for connecting the at least one sampling network input switch to a substrate; and at least one fifth switch for connecting the second terminal of the at least one capacitor to the substrate.
