Abstract
A sample and hold circuit including a charge path coupled to a voltage source. A first node of the charge path is located closer to the voltage source in the charge path than a second node of the charge path. The second node is coupled to an output of the sample and hold circuit to provide an output voltage. The sample and hold circuit includes a comparator circuit that compares the voltage of the first node and the voltage of the second node. When the comparator circuit determines that the voltage of the first node is a first condition with respect to a voltage of the second node, a voltage source provides a charging voltage on the first path to charge a first capacitor and a second capacitor to the charging voltage.
