: y. W+ {7 S3 [. SAbstract:A 1.8G H z C M O S low noise am plifier (L N A ) w ith transform er-type active inductor load is presented.
F or large inductance value, the quality-factor (Q) of an on-chip passive inductor is com m on ly low .
H ence, the purpose of this w ork is to verify th e validity of using transform er-type active inductor load as
% D: E! d! S" `substitutes for passive one. T he perform ance of the L N A is sim ulated and com pared w ith certain existing
L N A w ith passive on -chip inductor load w hich show s the L N A w ith transform er-type active inductor load
can achieve low er noise figure.
