Abstract
A distributed transistor model including linear dc crowding is analyzed. An expression for the short-circuit input impedance is derived for the cases of "very small" crowding and "large" crowding. It is found that in both cases the impedance is approximately equal to that of a transistor with no dc crowding and a shorter active base region. The effective length of the base region depends on the degree of crowding.
