In one aspect, an analog to digital converter (ADC) for a multiply-accumulator (MAC) system comprising: an ADC control that receives a VREF and generates a plurality of timing signals to an ADC, and wherein the plurality of timing signals comprises an Ssignal, an Ssignal, an Ssignal, an ECO signal, a CLOCK signal, and a COUNTER<N:0> signal; the ADC that comprises: a pre-charge system comprising a sense capacitor that stores an integrated charge IMAC over a time T and develops voltage VMAC, and wherein the Ssignal defines the pre-charge phase of the sense capacitor.

Methods and systems of utilizing analog to digital converter (ADC) for multiply-accumulator (MAC)

In one aspect, a method for NOR flash cell-array programming in a neural circuit includes the step of erasing a cell array. The method includes the step of programming a set of reference cells of a reference cell array to a target reference threshold voltage (V). The method includes the step of generating, with the reference cells, a current or voltage, reference signal. The method includes the step of using the reference signal to bias the neural cells during verification of program state of the neural cells to achieve their respective target threshold voltages (V). The method includes the step of programming a set of neural cells of a neural cell array to their respective target threshold voltages.

The method provides for a low power and a temperature independent analog to digital convertor for systems which use non-volatile cells for forming neurons to be used for neural network applications. The method uses a common counter which can be an up-counter or a down-counter depending on implementation, but in which the source and sink currents to a comparator are changed with temperature by the same percentage as the average bit line current for specific weight distributions programmed in the non-volatile cells forming the neurons. The method uses charge accumulation for detecting the average neuron current.
