Im not sure if i can make another new circuit, need to ask my teacher since she told me to modify the circuit the circuit to meet specs. im doing a assignment.

Ehh i changed the test bench, i did get a better gain, but BW n PM seems to become worst, and my dc simulation become a straight line, the same as input

1. Do a dc operating point simulation of a NMOS and PMOS with Vgs = 1V and Vds = 1.8V
2. Find out Id and Vth of both transistors from the operating point
3. Use the equation Id = 0.5µnCox(W/L)(Vgs - Vth)2 and calculate µnCox
4. Try this out for different values of W/L, Vgs and Vds.
5. With more values you can also find out λ (Channel length modulation parameter).
6. If you are interested, you can plot the Id vs Vgs curve by doing a dc sweep. You can then use curve fitting techniques to find out what is the whether the square law holds true. I have seen that for L = 0.18µm, the equation has a power of 1.32. You may not have to worry about this since you are using bigger lengths.
7. With the values of Kn and Kp in hand, do the procedure I gave you before.
