Abstract: The Low Noise Amplifier(LNA) plays an important role in the
receive system. It’s used to reduce the system noise, and improve the
receiver’s sensitivty. It’s the key-part in the receive system. This
article simply introduces the parameters of LNA’s , and the method of
design. It also shows the design, optimization, and simulation of the LNA
with ADS, and gives some advice solving the problems in t……
