TEMPERATURE COMPENSATION CIRCUIT AND METHOD FOR STORAGE AND OPERATION ARRAY OF NEURAL NETWORK

Disclosed in the present invention are a temperature compensation circuit and method for a storage and operation array of a neural network. A reference voltage is provided for an ADC by means of a reference array that is sparsely inserted in a storage and operation array, such that an input voltage of the ADC has the same temperature coefficient as the reference voltage, and finally the ADC is used to perform analog-to-digital conversion, such that a digital output of the ADC is not affected by an external temperature, thereby guaranteeing the operation precision of a neural network. The reference array used in the temperature compensation circuit according to the present invention has the same structure as a storage and operation array, the insertion density of the reference array is related to a temperature field in which the storage and operation array is located, one reference array can be used to simultaneously provide the reference voltage of an ADC for a plurality of storage and operation arrays, there
