Question

The maximum possible positive output signal swing as determined by the need to keep the transistor in the active region.

(a) -1.7 V

(b) -2.7 V

(c) -3.7 V

(d) -4.7 V

I had been asked this question during a job interview.

The question is from BJT in Amplifier Design in section Bipolar Junction Triodes (BJTs) of Electronic Devices & Circuits

Answer 1

Right option is (d) -4.7 V

To explain: The maximum voltage swing is given by -10 + 0.3 + (Ic X Rc). Putting Ic as 5 mA, we get -4.7 mV.
