Root

Dr. Abner Mallity has been working for a small electronics design company.
They need to produce a chip for a precise amplifier. Here the problems
they have.
-
They have a design for
an amplifier stage.
-
When they implement the
design the gain changes due to component variability, temperature (and
this is for a wide temperature range application).
-
They think that they can
use a feedback configuration to reduce the variability.
-
In the feedback configuration
they would use three stages.
-
Each stage has a nominal
transfer function of 100/(10-5s + 1)
-
The propose using a feedback
configuration like this one, but instead of unity gain in the feedback
path, they propose using a gain of .01.
Using root locus analysis,
determine if they can use this configuration.
