Recently, RF integrated circuit design based on CMOS
technology has receivedmuch attention owing to the low cost,
high integrability, and maturity. Low noise amplifier(LNA) is
the important element in the receiver for good sensitivity. In
this thesis, a single-ended 2.4GHz CMOS LNA is designed and
fabricated with cascoded source inductive feedback(SIF)
topology. An optimum noise performance and inputmatching is
examined to be simultaneously achieved using this topology. The
simulation result gets a NF of 2.9dB, a gain of 20dB at 2.4GHz,
and a P-1dB compression point referred to input of -28dBm.
Integrated planar inductor has the advantage not only size
reduction for band selection but also for optimum noise measure.
While the inductance and the related Q value are limited and are
not easily predicted because of the mutual coupling andresistive
Si substrate. This problem is overcome through using the full-
wave EM simulation. It is indicated that the quality factor Q
has been improved up to 50%.Thesimulation results are verified
to be closely to those by measurement. The error between the
simulation and the measurement are within 10-15%.
