Abstract
A computing device and method are provided. The computing device in some examples includes multiple digital-to-analog converters (DACs) having outputs connected to respective operational amplifiers, with outputs connected to the gates of respective transistors, each forming a serial combination with a respective memory element. The serial combinations are connected between a voltage reference point and a conductive line. An analog-to-digital converter is connected to the conductive line at the input. The DACs generate analog signals having ON-period lengths corresponding to the respective numbers at the DACs' inputs. The transistors generate currents indicative of the levels of output signals of the respective DACs and memory states of the respective memory elements for the ON-periods. The combined currents charge or discharge the conductive line to a voltage indicative of the sum of the numbers weighted by the memory states. The voltage is converted to a digital representation of the weighted sum.
