Claim:
1. A method of measuring semiconductor output characteristics comprising: applying a plurality of sets of repetitive pulses of voltage to a gate structure of a semiconductor device with a pulse generator, wherein a repeated pulse width of at least one of said plurality of sets of repetitive pulses of voltage is different from a repeated pulse width in a remainder of said plurality of sets of repetitive pulses of voltage that is applied to the gate structure; measuring an average current from a drain region of the semiconductor device for a duration of each of said plurality of sets of repetitive pulses of voltage applied to the gate structure; plotting a self-heating curve of the average current as a function of the pulse width; and extrapolating the self-heating curve to a value for the average current when the pulse width is substantially equal to zero to provide a value of drain current measurement without self-heating effects.
