Abstract
A tester includes a device under test (DUT) power supply (DPS) with and input and output includes an amplifier configured to set an output voltage of the DPS output equal to an input voltage for the DPS. The DPS has a first output stage coupled to the amplifier and configured to source and sink current at the output of the DPS between a first voltage rail and a third voltage rail. The DPS has a second output stage coupled to the amplifier and configured to source and sink current to the output of the DPS between a second voltage rail and the third voltage rail. A selection device is configured to enable the first and second output stages based on a selection input signal. The selection device is situated outside of the first and the second output stages.
