Abstract
A neural network controlled phase lock loop (PLL) with an artificial neural network for comparing the phase of the feedback signal from the voltage controlled oscillator (VCO) with the phase of the PLL reference signal. The VCO feedback signal and PLL reference signal are inputted to and processed by a multiple layer perception which has been trained with a model of the VCO to generate the appropriate control voltage necessary to establish and maintain the desired phase and/or frequency of the VCO output signal.
