D5.32 For a particular n-channel MOS technology, in which the minimum channel length is 0.2 μm, the associated value of λ is 0.5 V−1 . If a particular device for which L is 1.0 μm operates in saturation at vDS = 1 V with a drain current of 100 μA, what does the drain current become if vDS is raised to 2 V? What percentage change does this represent? What can be done to reduce the percentage by a factor of 2?
109 μA; 9%; double L to 2 μm
