Abstract
A neuromorphic analog signal processor includes a flexible circuit corresponding to an analog neural network. The flexible circuit includes operational amplifiers, each operational amplifier corresponding to an analog neuron. The flexible circuit also includes photoresistors or photodiodes interconnecting the operational amplifiers, and illumination sources. Each illumination source transmits light to a corresponding photoresistor or photodiode, thereby changing the resistance as a function of brightness of applied light. The flexible circuit also includes control circuits, each control circuit configured to apply a pulse-width modulation corresponding to a weight value, thereby causing pulsed signals at the illumination sources. The flexible circuit also includes a memory circuit coupled to the circuits. The memory circuit is configured to (i) store weight values corresponding to connections of the analog neural network and (ii) supply different weight values to the control circuits for different time periods.
