摘要
A self-timed reset pulse generator includes a flip-flop, a tracking block, and a tracking circuit. The flip-flop receives an input signal and a feedback signal and outputting a reset signal. The tracking block has replicating cells coupled in series and replicates a structure in an external device. The tracking block has a first terminal and a second terminal. The first terminal and the second terminal are taking from the tracking block at a same location or two different locations. The tracking circuit unit receives the reset signal and receives the first terminal and the second terminal for respectively discharging the tracking block at the first terminal and sensing a voltage level at the second terminal as triggered by the reset signal. A track-out signal serving as the feed back signal is output to the flip-flop when the voltage level is less than or equal to a threshold.
