Patent ID: 8504503

Claim:
An electronic circuit operationally representative of signal propagation between a first neuron and a second neuron, comprising: a circuit input node coupled to the electronic circuit; a circuit output node coupled to the electronic circuit, wherein a pulse energy of a circuit input signal at the circuit input node influences a circuit output signal at the circuit output node to take on a respective one of a plurality of discrete stable frequency states; and a CAN channel circuit, comprising: a CAN channel circuit input node at which a CAN channel circuit input signal is received; a log domain filter (LDF) configured to receive the CAN channel circuit input signal and configured to generate a filtered output signal; a wide range differential pair (WR-DP) comprising differentially coupled FETs coupled to receive a signal representative of the filtered output signal and configured to generate a wide-range output signal; and a current-generating circuit coupled to receive the wide-range output signal and configured to generate a CAN channel current signal (Ican) into the circuit input node, wherein the CAN channel circuit is representative of a biological CAN channel and wherein the CAN channel current signal is representative of a current passing between the first and second neurons.
