A CIRCUIT TO CHARGE A CAPACITOR

摘要

A power stealing circuit to charge a capacitor (18) includes a passive electrical power channel (14). The passive electrical power channel has an input (12) connected to an input signal and an output designed to be connected to the capacitor (18). An active electrical power channel (16) is powered by the capacitor (18). The active electrical power channel has an input connected to the input signal and an output connected to the capacitor.
