    Hi all,
    I would like to submit the following exercise (from Sedra-Smith book):

    Let us consider the 2 BJT large signal models shown on Figure attached (b) and (d). What are the relative dimensions of diodes DE and DB if transistor has ß=100? And if ß=1000?

    What I don't understand are the results reported on book. It says that in the first case the result is 11x and in the second one the result is 1000x.
    Are they correct?

    Thank you
