  • Publication number: 20240340023
    Abstract: Disclosed are a sigma-delta modulator that directly converts a current signal into digital data, an ADC utilizing the sigma-delta modulator, and a neural network computing system utilizing the ADC. The sigma-delta modulator includes: a delta circuit to generate a differential current between an analog current signal output from a resistive memory and a first current included in the analog current signal, the first current having an amount of current determined by a digital modulation signal; an integration circuit to generate an integration current by integrating the differential current; and a quantization circuit to generate the digital modulation signal corresponding to the integration current. The sigma-delta modulator can minimize the generation of noise by using no capacitor that performs a function by a switch, and can increase a signal processing speed for conversion by allowing the signal processing speed to be determined by a signal processing speed of one element.
