Abstract
Aspects of various embodiments of the present disclosure are directed to applications utilizing voltage sampling. In certain embodiments, a sample and hold circuit is configured to sample voltages that exceed a tolerance voltage of components. The circuit includes a first and a second capacitors. In a first mode, a voltage difference between an input node and a first reference voltage is sampled using the first capacitor. Also in the first mode, a voltage stored by the second capacitor is referenced to a second reference voltage and provided to a first output node. In a second mode, a voltage difference between an input node and a first reference voltage is sampled using the second capacitor. Also in the second mode, a voltage stored by the first capacitor is referenced to the second reference voltage and provided to a second output node.
