Abstract
A circuit for alternatively controlling a current through a device and permitting measurement of a voltage across the device or controlling a voltage across the device and permitting measurement of a current through the device includes a sense impedance in series combination with the device, an error amplifier selectable to control the controlled current or voltage, the error amplifier providing an error signal for the control, and a floating buffer driving the series combination in response to the error signal.
