hi,
Ive got a question that bothers me a little, small signal analysis is basically understanding that a linear relationship exists between Vbe & ic, this relationship is only valid if Vbe is less than 10mv, and it implies that the transistor behaves as a voltage controlled current source when vbe, the input signal between base and emitter is less than 10mv, im fine with that, but lets say i input 10mv into a transistor with a gain of 10, then the output voltage will be 100mv, say i wanted to input that 100mv into a second transistor, would the linear model still apply, i'm getting really confused over this.
Any help is welcome thanks.. H
