Question

Where is the output measured in a common base transistor physical model?

(a) Collector terminal

(b) Emitter terminal

(c) Base terminal

(d) Ground

I had been asked this question in exam.

I'd like to ask this question from Physical Model of a CB Transistor in division Small-Signal Low-Frequency AC models of Transistors of Electronic Devices & Circuits

Answer 1

The correct option is (a) Collector terminal

To explain I would say: In the physical model of a common base transistor amplifier the output is measured at the collector terminal of the BJT biased device. Whereas, the input is measured across the emitter terminal of the biased BJT device.
