Even though mechanisms that makes bipolar transistor run are quite complica ted and there are many side effect to be covered, simple analysis is possi ble with two simple models: one for active regime, when we use one independ ent voltage source to model base-emitter p-n junction and one current contr olled current source to model collector-emitter junction. Another is model of bipolar transistor that takes only two independent voltage sources. Read more.

Largely beginner stuff.
'Reverse-active is when collector-base PN junction is forward biased and ba se emitter PN junction is reverse biased (just opposite to active mode). In this mode, hFE is with value from few hundreds to few tens of times lower then hFE in active mode (with value of typically from 1 to 50). This mode i s used only in input stage TTL logic circuit and nowhere else.'
I thought it was also used for rf work, reducing Miller capacitance

Wouldn't you make more money begging in the streets?

street, barroom what's the difference, it's an after work stop off :)

Methinks you're being too subtle for this guy.
