Im studying the equivalent model of a BJT common emitter amplifier at high frequencies.At university we tought that the BJT at high frequencies looks something like this:
However when designing a common emitter amplifier we have to take into account any base resistors .So I draw this diagram but I dont know if it is correct.Should the base resistor be before Rx or after?
