Lambda =1/VA 7 2 Kumar Ankit Then write down your equation using channel length modulation and isolate gds on the right hand side. In the figure at the right, the channel is indicated by a dashed line and becomes weaker as the drain is approached, leaving a gap of uninverted silicon between the end of the formed inversion layer and the drain (the pinch-off region). All Rights Reserved. Channel Length Modulation After pinch-off occurs at the drain end, the length of the inversion layer and, hence, the channel resistance continually decrease as the drain bias is raised above VD, sat. +XL = 0 XW = -4E-8 DWG = -1.5E-8 Change in voltage is due to N, so N is the slope of the I-V in the saturation region.
