Abstract
An apparatus for providing a supply voltage to a device under test includes a controlled source configured to provide a voltage in dependence on one or more control signals; a switchable resistor circuited between the output of the controlled source and a DUT port, having first and second resistances in first and second switch states, respectively, the second resistance being smaller than the first resistance; a regulator configured to provide a control signal to the controlled source, to regulate a voltage to be provided to the DUT in dependence on information about a desired voltage; a capacitor circuited in parallel to the switchable resistor at least during switching of the switchable resistor and configured to slow a voltage change across the switchable resistor which is caused by changing a switch state of the switchable resistor; the apparatus being configured to change a switch state of the switchable resistor while a voltage is provided to the DUT via the switchable resistor.
