Page 1 of 6 EE 230 Homework 10 Spring 2010 Problem 1 Assume the transistor M 2 shown below is characterized by the model on the last page of this HW assignment. Determine I X. Problem 2 If the Op Amp is ideal and R 2 =50K, determine the gain of the amplifier if V CONT =4V. Assume the transistor has dimensions W=10u, L=6u. and that it is modeled by the parameters V T =1V, uC OX = 1E-4 A/V 2 , and λ =0V -1 .

Page 2 of 6 Problem 3 Determine V OUT if the resistor R=5K and the transistor has dimensions W=10u, L=1u. . Assume the transistor is modeled by the parameters V T =1V, uC OX = 1E-4 A/V 2 , and λ =0V -1 . I D 5V 2V 2 OUT Problem 4 If a transistor has gate dimensions of W=45nm and L=45nm, how many transistors could be placed in an area equal to the cross-section of a 24ga copper wire? (neglect any spacing requirements between the transistors – this assumption introduces an error in the number of transistors that is somewhere around a factor of 10).
