it is said that mos has a resistive channel, so it has thermal noise, just like other
resistor. But the gate resistance is huge, in this way is it will exhabit thermal nosie?
Noise of poly gates is not important if it is low frequency because gate is floating, however in the case of LNA you have to decrease the resistance of poly.

Yes, I believe so. High resistance of gate to channel can be represented as a shunt resistance. You can convert the shunt resistance to the series one using 4-port network and find out that high shunt resistance coresponds to low series one.
