maximum linear transconductance (gm(max))
The maximum slope of the ID-VGS curve in the linear region.
NOTE 1 The gate voltage is varied in increments no greater than 20 mV from below the turn-on voltage to a value great enough to ensure that the maximum slope point has been reached.
NOTE 2 The slope is calculated using a three-point linear least-squares best-fit algorithm as defined in ASTM F617‑86.
