DISTRIBUTED BOOTSTRAP SWITCH

摘要

An input circuit for an analog-to-digital converter (ADC) includes at least one bootstrap circuit, including at least one first switch (SW1:308) for connecting electrical power (VDD) to a first terminal of at least one capacitor (C:304); at least one second switch (SW2:310) for connecting a second terminal of the at least one capacitor to a signal (VIN) to be sampled; at least one third switch (SW3:312) for connecting the first terminal of the at least one capacitor to the control gate (309) of at least one sampling network input switch (306); at least one fourth switch (SW4:314) for connecting the at least one sampling network input switch (306) to a substrate; and at least one fifth switch (SW5:316) for connecting the second terminal of the at least one capacitor to the substrate.
