Abstract
A circuit is provided for limiting an applied voltage applied between a power line and an electrical ground. The circuit includes a transistive element connected between the power line and the electrical ground to provide a channel, where current flow through the channel is controlled by a control voltage provided to a control terminal of the transistive element. A first Correlated Electron Material (CEM) device having an impedance state is coupled between the power line and a first node, and a sensing circuit coupled between the first node and the control terminal of the transistive element. The sensing circuit is configured to detect a voltage drop across the CEM device and to provide the control voltage. The channel of the transistive element is opened when the detected voltage drop across the CEM device exceeds a threshold. The CEM device may contain a transition metal oxide (TMO), for example.
