專利摘要(英)
A dynamic differential-reference time-to-digital converter for computing-in-memory applications is controlled by a bias reference and a predetermined setting parameter, and includes a configurable main-reference selector and a plurality of time-to-digital converters. The configurable main-reference selector is configured to receive a plurality of edge-output signals, select one of the edge-output signals as a main reference and select others of the edge-output signals as a plurality of edge selected signals according to the predetermined setting parameter. One of the time-to-digital converters is configured to compare the bias reference with the main reference to output a bias multiplication-and-accumulation value, and others of the time-to-digital converters are configured to compare the main reference with the edge selected signals to output a plurality of differential multiplication-and-accumulation values. The bias multiplication-and-accumulation value and the differential multiplication-and-accumulation values are dynamically adjusted according to the bias reference and the predetermined setting parameter.
