Abstract

PURPOSE: To detect to a degree of 0.01V, the voltage drop in electronics wrist watches using low voltage source by converting pulse output that fluctuates due to voltage into two signals that varies their phase-pholds, and by detecting these phaseholds and measuring their voltage fluctuations.
