2 7. Below are two schematics of current sources implemented with MOSFETs. Which current source has the best compliance voltage? (a) (b) 8. True or false: in IC circuits, transistors are often used to replace resistors, because IC realestate is expensive, and resistors, especially large value resistors, require large surface area. 9. True or false: assuming that g m1 = g m2 for the amplifiers below, then A v1 is larger than A v2. However, A v1 also more sensitive to FET parameter variation than A v2. 2

Consider two MOSFETs A and B that are identical in all respects except that A s channel is twice as wide as channel B s channel: W A = 2W B. Under identical bias what is the relationship between the drain current of A and B? I DA = 13. Consider two MOSFETs A and B that are identical in all respects except that A s channel is twice as long as channel B s channel: L A = 2L B. Under identical bias what is the relationship between the drain current of A and B? I DA = 14.
