A transistor has hie =2kΩ, hoe=25µmhos and hfe=60 with an unbypassed emitter resistor Re=1kΩ. What will be the input resistance and output resistance?
(a) 90kΩ and 50kΩ respectively
(b) 33kΩ and 45kΩ respectively
(c) 6kΩ and 40kΩ respectively
(d) 63kΩ and 40kΩ respectively
I got this question in an interview for job.
I would like to ask this question from The AC Analysis of a Small-Signal Low-Frequency Common Emitter Transistor. topic in chapter Small-Signal Low-Frequency AC models of Transistors of Electronic Devices & Circuits
