WebBJT Circuits • Most electronic devices take the signal between two input terminals and deliver from it an output signal between two output terminals. • The BJT has only three terminals so one of these is usually shared (i.e. made common) between input and output circuits. • We thus talk about common emitter (CE), WebApr 9, 2024 · Confusion about the meaning of re and rπ. In BJT small-signal models there is both r e and r π parameters. They both represent the dynamic resistor between the base and the emitter terminals. I know the concept of transconductance gm. It is the slope of the Ic Vbe plot at a fixed bias collector current i.e: gm =∂Ic/∂Vbe.

WebOct 13, 2014 · The op must clearly have an emitter resistor given what he says for the current. Q1 is an emitter follower, so R3 is not needed. If you want to scale the design to use a higher voltage source ie 12v instead of 5 for example you would want to use PNP transistors for the high side switching and than you would need a base resistor.
