I still have memories of some analog switching done with bipolars , only
using reverse saturation (collector reversed with emmitter - picture a npn
with the emmitter tied at a more positive potential than the collector) .
The trick was yielding lower Uce in saturation. Lots of people were quick to
point out that the schematic had an error ;)
