Electronic Devices and Circuits - Section 2 Question & Answers

Electronic Devices and Circuits - Section 2 Question & Answers A Schottky diode clamp is used along with switching BJT for A. reducing the power dissipation B. reducing the switching time C. increasing the value of β D. reducing the base current - ANSWER: B An incremental model of a solid state device is one which represents the A. ac property of the device at desired operating point B. dc property of the device at all operating points C. complete ac and dc behaviour at all operating points D. ac property of the device at all operating points - ANSWER: A As temperature increases A. the forbidden energy gap in silicon and germanium increase B. the forbidden energy gap in silicon and germanium decrease C. the forbidden energy gap in silicon decreases while that in germanium decreases D. the forbidden energy gap in silicon increases while that in germanium decreases - ANSWER: B Therefore, conductivity increases. Assertion (A): A decrease in temperature increases the reverse saturation current in a p-n diode.
