Variable-bit adaptive sensing circuit system in analog neuromorphic systems

Abstract

A variable-bit adaptive sensing circuit system in an analog neuromorphic system is disclosed. In an analog neuromorphic system including a synapse array, the circuit system for sensing the synapse array comprises: a sensing part circuit configured to sense output currents of synapse devices in each column of the synapse array in response to an operation signal; an error detection circuit configured to detect errors based on the column-wise output currents of the synapse devices and determine an operation start reference; and an analog-to-digital conversion circuit configured to integrate the synapse device current based on the operation start reference, convert the integrated current into a voltage value, and output a corresponding digital value.
