Abstract
A power supply is disclosed for use with a device-under-test disposed on a device board. The power supply includes a high-accuracy remote supply circuit including respective force and sense lines and a high-speed local supply circuit. The local supply circuit includes an active boost circuit having respective boost and sense lines coupled to the force and sense lines. The active boost circuit is operative to selectively cooperate with the remote supply circuit and, when the device-under-test demands a large dynamic current, provide the dynamic current until the remote supply circuit responds to the current demand.
