Abstract
The present invention relates to a circuit that pulls down the power supply line in an electronic system to a low state when the electronic system is turned off. More specifically, the present invention is an active circuit that establishes a low impedance between a power supply line and a return line when a system's power is turned off, and establishes a high impedance between a power supply line and a return line when the system is turned on.
