Abstract
A non-linear circuit includes a first variable resistor one end of which is applied with an input signal, an amplifier whose inverting input is connected to the other end of the first variable resistor and whose non-inverting input is connected to ground, a second variable resistor one end of which is connected to the inverting input of the amplifier, a third variable resistor one end of which is connected to the output of the amplifier and the other end being connected to the other end of the second variable resistor, and a fourth variable resistor one end of which is applied with the input signal and the other end being connected to the third variable resistor. A chaotic neuron circuit using the non-linear circuit includes a first sample-and-hold circuit for sampling the input signal in response to a first clock signal, a non-linear circuit for generating an output signal having a non-linear characteristic with respect to the output of the first sample-and-hold circuit, an adder for summing the output signal of the non-linear circuit and an external input signal, a second sample-and-hold circuit for sampling the output of the adder in response to a second clock signal and for outputting the result to the input of the first sample-and-hold circuit, and a clock generator for generating the first and second clock signals. The non-linear circuit and the chaotic neuron circuit using the same have a simple constitution.
