EE 435 Name ________________________ Final Exam Spring 2005 Instructions: There are 6 problems, all equally weighted. If reference to a semiconductor process is needed, assume a process with the following key process parameters. If any other process parameters are needed, specify clearly what process parameter is needed and specify a typical value for that parameter. μ n C OX =100 μ A/v 2 μ p C OX =30 μ A/v 2 V TNO =0.5V V TPO = - 0.5V poly sheet resistance ρ ΝΟΜ = 50 ohms/sq poly sheet resistance local statistical variation parameter, A ρ =0.1 ohms transistor local statistical variation parameters for both n-channel and p-channel devices A VTON = A VTOP = 20mV . μ A L = A W = 0.
