Find for an n-channel transistor having doping concentrations of and with , , , and . Assuming remains constant, estimate the new value of if is increased by .

A MOS transistor in the active region is measured to have a drain current of when . When is increased by 0.5 V, increases to . Estimate the output impedance, , and the output impedance constant, .
