Vin 2k M + 1k V out VG Assume that the op-amp is ideal. For the transistor M, use K = 2mA/V² and VT = 1V. For the rest of the circuit, use Vin = 2V and VG = 5V. (a) In terms of voltages shown on the diagram, what are VD and V3? Why? (b) Determine Vout and the current flowing out of the output terminal of the op-amp. (c) What mode is the transistor in? Verify that the conditions of that mode are satisfied. (d) Replace the 2kn resistor with a short circuit (wire). 1. Without doing any calculations, what mode you expect the transistor to be in? Why? 2. Show that the transistor is in this mode.

Question
2k M + 1k V out VG Assume that the op-amp is ideal. For the transistor M, use K = 2mA/V? and Vr = 1V. For the rest of the circuit, use Vin = 2V and VG = 5V. (a) In terms of voltages shown on the diagram, what are Vp and V3? Why? (b) Determine Vout and the current flowing out of the output terminal of the op-amp. (c) What mode is the transistor in? Verify that the conditions of that mode are satisfied. (d) Replace the 2kn resistor with a short circuit (wire). 1. Without doing any calculations, what mode you expect the transistor to be in? Why? 2. Show that the transistor is in this mode. Show your work for full credit. NOTES and SUGGESTIONS For this problem, you should replace the transistor with its equivalent model. For a full credit on part (c), you need to solve the circuit for both Triode and Saturation mode, showing that the criteria are met for one mode and are not met for the other. For part (d1), part of your explanation should be why it cannot be in the "other" mode. Be mindful of the directions of current when solving this problem.
