Abstract: A system includes an amplifier to receive a signal, an analog-to-digital converter (ADC), a first switch coupled to a capacitor to receive an output from the amplifier, the capacitor to provide the output to the ADC, a second switch coupled between the capacitor and the ADC to turn on/off the ADC, a third switch coupled between the amplifier and the first switch to connect/disconnect the output to/from the first switch, a fourth switch coupled between the amplifier and the first switch to bypass the amplifier, and circuitry. The circuitry turns on the first switch and the second switch to initiate charging the capacitor, turns on the fourth switch and turns off the third switch to complete the charging, and turns off the second switch and the first switch to control the ADC to convert the output to a digital signal.
