Re: LNA Gain peaking at wrong frequency?
Reply #2 - Dec 17th, 2004, 3:44pm
You can increase the Lg to move peak to the right but remember you'll pay for the power gain in terms of NF. It'll go up. If you have little margin for NF, your only choice is to increase the gain. Here's how you increaes the gain:
1) decrease Ls 2) increase W/L ratio 3) Add another Common Source stage with inductive degeneration.
I hope it helps.
