A single-pole op-amp has an open-loop low-frequency gain of A = 10 5 and an open loop, 3-dB frequency of 4 Hz.

If v GS changes with 1 mv, by how much does the drain current change? 3. The units for the λ parameter for a MOSFET is 4. The op-amp in the circuit is ideal, and R 1 = 10K, R 2 = 100K, and R 3 = 10K. The input resistance that the source sees is (a) R 1 = 10K (b) R 1 + R 3 = 20K (virtual short between + and ) (c) (Ideal op-amp has R i = ) (d) R 1 R 2 R 3 = 4.72K (KCL at terminal) 5.

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

True or false: everything else being equal, MOSFETs the drain current is directly proportional to the width-to-length ratio. 12. 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. True or false: given the symmetrical construction of MOSFETs one can, in principle, at least, interchange the drain and the source terminals without affecting device behavior. 15.
