Closed-form expressions to estimate power supply noise due to the simultaneous switching of I/O drivers are revisited in this brief. It is shown that existing closed-form expressions share a common limitation and underestimate noise with up to 83% error in advanced nanoscale technologies with fast signal rise/fall times. This characteristic is investigated, both quantitatively and qualitatively. New closed-form expressions are developed for the signals with fast transition times. Results… CONTINUE READING
