X-Controlled Memristive Devices for Automatic Gain Control in RC Oscillators

Classical memristive systems, also referred to as the extended memristors, are generalized to memristive systems whose internal state can be controlled via the voltage or current of an auxiliary port. The usefulness of these proposed devices is illustrated on the example of AGC (Automatic Gain Control) of RC oscillators. The parameters of the corresponding memristive systems required for a smooth startup and low harmonic distortion of the oscillation signal are formulated. It is shown that this concept includes some hitherto employed methods of gain control as special cases, and that its key added value consists in the possibility of nanoscale implementation.
