Abstract
An apparatus and method for measuring battery voltage includes a first capacitor configured to receive a charge from a battery. A first switch may be configured to selectively couple the first capacitor to the battery. A second capacitor may be coupled to a reference potential. A second switch may be configured to selectively couple the second capacitor to the first capacitor to transfer at least a portion of the charge on the first capacitor to the second capacitor.
