Abstract
An electronic device may include wireless circuitry having analog-to-digital converter (ADC) circuitry. The ADC circuitry may include a sampling switch coupled to a bootstrap circuit. The bootstrap circuit may include a bootstrap capacitor, a first transistor coupled between an input of the sampling switch and a bottom plate terminal of the bootstrap capacitor, a second transistor coupled between the bottom plate terminal of the bootstrap capacitor and ground, and a resistor or transistor that is disposed between the first transistor and the bottom plate terminal of the bootstrap capacitor and that is configured to boost the input impedance of the bootstrap circuit.
