D5.31 In a particular IC design in which the standard channel length is 0.18 μm, an NMOS device of standard length with W/L of 10 operating at 100 μA is found to have an output resistance of 20 kΩ, about of that needed. What dimensional change can be made to solve the problem? What is the new device length? The new device width? The new W/L ratio? What is VA for the standard device in this IC? The new device?
