Abstract
A computing-in-memory circuit comprises a computing element array and an analog-to-digital conversion circuit. The computing element array is utilized for analog computation operations. The computing element array includes memory cells, a first group of computing elements, and a second group of computing elements. The first group of computing elements provides capacitance for analog computation in response to an input vector and receives data from the plurality of memory cells and the input vector. The second group of computing elements provides capacitance for quantization. Each computing element of the computing element array is based on a switched-capacitors circuit. The analog-to-digital conversion circuit includes a comparator and a conversion control unit. The comparator has a signal terminal, a reference terminal, and a comparison output terminal, wherein the first and second groups of computing elements are selectively coupled to the signal terminal and the reference terminal.
