a) intrinsic semiconductor b) direct semiconductor c) degenerate semiconductor d) indirect semiconductor

20.When operating as a voltage regulator, the breakdown in a Zener diode occurs due to the
a) tunneling effect b) avalanche breakdown c) impact ionization d) excess heating of the junction.

21.If the common base DC current gain of a BJT is 0.98, its common emitter DC current gain is
a) 51 b) 49 c) 1 d) 0.02

22.Negative resistance characteristics is exhibited by a
a) Zener diode b) Schottky diode c) photo diode d) Tunnel diode

23.Let En and Ep, respectively, represent the effective Fermi levels for electrons and holes during current conduction in a semiconductor. For lasing to occur in a P-N junction of band-gap energy 1.2 eV, (En – Ep) should be
a) greater than 1.2eV b) less than 1.2eV c) equal to 1.1eV d) equal to 0.7eV

24.In a P-well fabrication process, the substrate is
a) N-type semiconductor and is used to build P-channel MOSFET
b) P-type semiconductor and is used to build P-channel MOSFET
c) N-type semiconductor and is used to build N-channel MOSFET
d) P-type semiconductor and is used to build N-channel MOSFET

Remaining questions are in the attachment, please click on it……..
