I'm a student who is studying RFIC with Razavi's textbook.
Could i get an detailed explaination about question
(b)?
Problem 1. Fig. 1 shows three amplifier candidates for LNA. For each LNA, calculates following. Neglect flicker noise, body effect, channel length modulation, and the parasitic capacitances. (Point: 40) Amplifier 1 Amplifier 2 Amplifier 3 J M₂,9m2 M₂, 9m2 RL Rs CB Rs CB M1,9m1 WWII M1,9m1 WH M1,9m1 ww Vin Vin RB Vin VB Figure 1. Three amplifier candidates for LNA (a) Input impedance and describe what should you do for input impedance matching (b) From the results of (a), let's assume that you did impedance matching. What is the noise factor for each LNA? (c) From the results of (b), which one has the lowest noise factor? And why? Zin Vout VB Zin Rs CB RF Vout Zin RF Vout
