A comparison of experimental results to those in "evaluation of bipolar junction transistor transconductance in practical applications"

An attempt to recreate the experimental results given in the paper by C.D. Ferris (see ibid., vol.36, p.293-5, 1993) was made using a modern transistor curve tracer. The experimental results were not reproduced. The new experimental results seem to validate the common usage of /spl eta//spl ap/1 in describing bipolar junction transistors.
