this is with reference to the article published in RF DESIGN march 2002.we can optimize simultaneosly the lna i/p reurn loss and lna noise figure by using inductive feedback and by adjusting load reflection coefficient.my problem is to find out for what values of load reflection coefficient and the amount of inductor feedback is required we have to map load reflection on to the input plane in smith chart using following equation

Tin=S11 +S12 S21 Tl

-------------

1-S22Tl

where Tin----input reflection coefficient

Tl-----load reflection coefficient

how to plot this in genysys

any suggestions are welcome
