Amplifier systems for measuring a wide range of current are provided herein. In certain embodiments, an amplifier system includes a controllable sensing circuit, a first amplifier including an output configured to drive a device under test (DUT) through the controllable sensing circuit, and a second amplifier including an input coupled to the controllable sensing circuit and operable to generate a measurement signal indicating an amount of measured current of the DUT. The amplifier system further includes a control circuit operable to control a configuration or mode of the controllable sensing circuit suitable for a particular type of DUT.

Amplifier systems for measuring a wide range of current

Apparatus and methods for setting and clamping a node voltage are provided herein. In certain embodiments, a node control circuit includes a setting circuit for setting a voltage of a node based on a set signal. The node control circuit further includes at least one of a p-type follower clamp for clamping the node to an upper voltage limit based on an upper clamping control signal or an n-type follower clamp for clamping the node to a lower voltage limit based on a lower clamping control signal. When including both clamps, the node operates with a voltage level set by the set signal, but saturates at the upper voltage limit established by the upper clamping control signal and at the lower voltage limit established by the lower clamping control signal.
