Abstract
Measuring circuits including switched capacitors, and related systems, methods, and devices are disclosed. A measurement circuit includes a flying capacitor, a grounded capacitor, a first switch, a second switch, a third switch, and a fourth switch. The first switch is configured to selectively electrically connect an electrochemical cell cathode node to a first terminal of the flying capacitor. The second switch is configured to selectively electrically connect an electrochemical cell anode node to a second terminal of the flying capacitor. The third switch is configured to selectively electrically connect the first terminal of the flying capacitor to a third terminal of the grounded capacitor. The fourth switch is configured to electrically connect the second terminal of the flying capacitor to a fourth terminal of the grounded capacitor. The fourth terminal is electrically connected to the reference voltage potential node.
