Nonlinear Function Generators and Chaotic Signal Generators Based on Pulse-Phase Modulation

This paper proposes a new arbitrary nonlinear transfer function generator circuit based on pulse-phase modulation. The circuit can generate an arbitrary non-monotone function with an identical circuit con guration. Chaotic signal generators using this function generator are also proposed. Circuit simulation results demonstrate that the new approach achieves high precision transformation. These circuits can be used for VLSI implementation of advanced neural networks such as associative memory models using non-monotone activation functions and chaotic neural networks.
