PIN diode

Tunnel diode

Unijunction transistor (UJT)

Solution:

Loudness control provides:

High boost to bass and little boost to treble

Equal boost to bass and treble

Less boost to bass and more boost to treble

Less boost to both bass and treble

Solution:

An amplifier uses negative feedback to increase the input resistance and output resistance. What is the suitable feedback topology?

Shunt-Shunt

Shunt-Series

Series-Series

Series-Shunt

Solution:

What would be the maximum quantum efficiency (in %) possible for a photodiode, upon which an optical pulse containing 8 x 106 photons is incident and produces 6.5 x 106 electron-hole pairs?

Solution:

Which of the following oscillators is suitable for applications whose frequencies are in the range of megahertz (MHz)?

Hartley Oscillator

RC phase shift oscillators

Wien-Bridge Oscillators

None of the above

Solution:

Tasha was given a wide range of equipment by her teacher to check the condition of a diode.
The equipment given are as follows:
i) Digital Display Meter
ii) Ohmmeter
iii) Curve Tracer
iv) CRO
Which of the following equipment cannot be used to check the condition of a diode?

i and ii

only iii

iii and iv

only iv

Solution:

In a current mirror circuit, the reference current (I_o) is 5 mA, and a MOSFET (M1) connected to the reference current source has dimensions (W/L)₁ = 4. The dimensions of MOSFET (M2) to which the reference current is copied have (W/L)₂ = 8. What is the current (I_x) flowing through MOSFET M2?

5 mA

10 mA

15 mA

2.5 mA

Solution:

Assertion (A): Two transistors, one n-p-n and the other p-n-p, are identical in all respects (doping, construction, shape, size). The n-p-n transistor will have better frequency response.

Reason (R): The electron mobility is higher than hole mobility.

Both A and R are true and R is the correct explanation of A.

Both A and R are true but R is not the correct explanation of A.

A is true but R is false.

A is false but R is true.
