Summary: As pure analog circuits cannot address the noise accumulation problem, a practical solution would also require inclusion of analog-to-digital and digital-to-analog stages for signal restoration. High energy-efficient and compact data converters are therefore expected to play an important role in future computing platforms. We perform an experimental demonstration of 6-bit digital-to-analog (DAC) and 4-bit analog-to-digital conversion (ADC) operations implemented with a hybrid circuit consisting of Pt/TiO2-x /Pt resistive switching devices (also known as ReRAMs or memristors) and a CMOS operational amplifier (opamp). In particular, ADC is implemented with a Hopfield neural network circuit.
