Abstract

The techniques and circuits, described herein, include solutions for reducing measure current settling time in source measurement units (SMUs) during a force voltage mode of operation. An SMU includes a force amplifier having a first voltage input, a second voltage input, a feedback voltage input, and a output. A resistor has a first terminal coupled to the output of the force amplifier, and a second terminal. A switch is coupled between the second terminal of the resistor and the feedback voltage input of the force amplifier. The switch is closed in the force voltage mode, creating a feedback path which the resistor is contained within. A series combination of a capacitor and a resistor is coupled to a gate of a transistor within the force amplifier, which results in improved measure current settling time compared to alternative techniques.
