Modeling of Memristive and Memcapacitive Behaviors in Metal-Oxide Junctions

Figure 3

Schematic diagram of the variable capacitor model using a controlled voltage source and a separate integrator circuit to calculate charge by integration of current as in (a) or a controlled current source and a separate differentiator circuit to calculate the differentiation of voltage as in (b). The capacitance is considered to be controlled by a function which can be chosen to be dependent on the applied voltage, the passing charge, or any other variable.
