On-Chip Driver output slew rate measurement method is described. Recently the Driver that has some slew rate control or the slew rate is important has been developed. To measure the slew rate of such Driver, some special instruments are required. By using this new method, it is possible to measure slew rate without any additional instruments and it also can be measured "On-Chip". Figure-1 shows the new proposed circuit. Figure-2 shows the timing chart of each node. As shown in the figure, Driver output is fed back into the circuit on the same chip. And then it becomes possible to measure Driver output slew rate on the same chip.
