Abstract
A circuit includes a fuse and a sensing and control circuit. The fuse is coupled between a MOS transistor and a current source node. The sensing and control circuit is configured to receive a programming pulse and output a modified programming signal to the gate of the MOS transistor for programming the fuse. The modified programming signal has a pulse width based on a magnitude of a current through the first fuse.
