Topic 49: Transconductance Comparison

I made a mistake writing the equation for dynamic emitter resistance re. I think I might be slightly dyslexic (I do transpose digits, etc. fairly often). Anyway, the emission coefficient (eta) multiplies the numerator V_T and not the denominator Ic as shown. Sorry about the confusion.
This is a more qualitative video comparing the transconductance of the devices we've been looking at so far in this series of videos. The curves for the MPF201, LND150, DN2535, 2N7000 and the 2N3904 are graphed on the same scale, making comparisons particularly easy.
