I have the following differential pair circuit that is designed to have a diff gain of 4 V/V and a power consumption of 1mW. The transistor should be biased to have a Veff=0.3V and should have a length of 0.25um. With uCox = 270 and Vt=0.45V. I should determine W in the transistors and the values of RD and Ibias. Do you have any idea of how can I find these parameters? I have some equations but I got to a point that doesn't make sense. Where should I account on the consumption power?
