Abstract:
An active shunt source-measure unit (SMU) circuit can include an SMU or power supply having an active shunt circuit that is integrated with the current measuring sub-circuit of the SMU circuit. The active shunt circuit may be active during voltage sourcing of the SMU circuit and deactivated during current sourcing of the SMU circuit.
