Initially, choose 
. Compute the output stability circle and
to check whether the position of 
is sufficient far away from
the output stability circle, if not, change 
to accept higher noise based on the
overlay of noise circles. For a given choice of , compute the input stability
circle and overlay with constants operating gain circles. Choose a load termination on the gain circle which has
the value of the specified gain and it should be in the stable region and far away the
input stability circle, if not, change to accept higher noise based on the
overlay of noise circles. And repeat the whole process such that a compromise can be reached
on the value of noise figure and stability. Usually we can obtain higher gain values for a
degradation in the noise figure.
