4 `/ F0 \* Q+ P( qF 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
substitutes for passive one. T he perform ance of the L N A is sim ulated and com pared w ith certain existing
