Pipelined Memristive neural network analog-to-digital converter

Abstract

This paper designs a pipelined memristive neural network ADCs. Cascade the sub stages of memristive neural network ADC with pipeline structure to improve the conversion accuracy of memristive neural network ADC. First, the signal flow of the pipeline architecture is optimized, and the compatibility between the 4 bit memristive neural network ADC and the pipeline architecture is solved. Secondly, the application of random disturbance circuits in pipeline architecture was analyzed. Combining the calibration circuit with the pipeline DAC to reduce the power consumption of the calibration circuit. Finally, the circuit model of memristive neural network ADC is built and compared with the existing memristive neural network ADC. The results indicate that the pipeline structure ADC designed in this chapter has the advantage of adaptive calibration in terms of calibration function.
