Abstract

A reservoir computing method and related system. The method comprises providing a pulse wave representation of a reservoir input and a MOSFET-based compute node of a reservoir computing system. A body terminal of the MOSFET is configured to apply a bias signal to the body region. The MOSFET is operable in floating mode in the absence of the bias signal. The MOSFET displays a history-dependent threshold voltage when driven by input pulses in floating mode. The method further includes removing the bias signal from the body terminal; applying input pulses to a gate terminal of the MOSFET, thus causing history-dependent variations in the threshold voltage; and acquiring an output sequence related to the compute node while the MOSFET threshold voltage is varying, by repeatedly applying readout pulses to the gate terminal of the MOSFET and simultaneously detecting a current through a channel region of the MOSFET.
