Abstract: A tunable CMOS circuit comprising a CMOS element and a tunable load. The CMOS element is configured to receive in an analogue input signal. The tunable load is connected to the CMOS element and configured to set a switch point of the CMOS element. The CMOS element is configured to output an output current that is largest when the analogue input signal is equal to the switch point. The combination of a CMOS element with a tunable load may also provide a hardware implementation of fuzzy logic. A fuzzy logic gate comprises an input node, a CMOS logic gate including a tunable load, and an output node. The input node is configured to receive an analogue input signal. The CMOS logic gate is connected to the input node. The tunable load is provided on a current path connected to the output node. The output node is configured to output an analogue output signal.

Abstract: The present invention provides a method and system for processing data from an event, such as a neurological event. When a neurological event occurs, a spike in a neural waveform is generated. The spike can be detected and used to determine information about the neurological event. The method uses data values from a resistive switching component capable of undergoing a resistive state change when a voltage is applied to it. The data values represent a sequence of resistive state changes of the resistive switching component which correspond to the neurological event. The method further comprises processing the received data values to identify a resistive state change corresponding to the neurological event and to obtain information about the neurological event. Thus, a method and system for processing neural spikes is provided.
