ABSTRACT:
A bi-directional current scaling preamplifier is inserted between a device under test and a source measure unit or a source measure unit and switching matrix combination. The bi-directional current scaling preamplifier is formed from an operational amplifier, a range-changing network, and a voltage to current converting circuit. Either the network or the converting circuit is provided with an inverter. The elements are arranged so that current from the source measure unit into the device under test is bi-directionally scaled.
