System and method for using stored electrical energy to quiet power sensitive measurement circuits

摘要

The present invention is a system and method for temporarily storing electrical energy to power sensitive measurement circuits. In one embodiment, a switch-mode power converter is operable to charge an energy storage device. After the energy storage device is sufficiently charged, the switch-mode power converter is powered off so that sensitive measurements may be made without being affected by noise or interference caused by the switch-mode power converter. Once the measurement has been made, the switch-mode power converter is powered on and provides power to the energy storage device to recharge the energy storage device so that a subsequent measurement may be made.
