Question

Derive and explain Miller Effect Capacitance (BJT).

Answer #1

What is the Miller effect? Explain how it arises in an NPN
transistor?

derive the expression for the capacitance of a nanotube sitting
on a Si/SiO2 substrate

Derive the relationship for the output voltage chnage assuming an
ideal capacitance across the load.

Derive the expression for Capacitance of a nanotube sitting on a
Si/SiO2 substrate. And calculate C for a 1nm Carbon
Nanotube on 50 nm SiO2 on Si.

a. Derive the capacitance of a cylindrical capacitor with inner
plate radius w1, outer plate radius w2, length z, and dielectric
constant kappa and determine how the capacitance is affected if the
dielectric constant is doubled while the length is halved.
b. A parallel-plate capacitor contains two layers of equal
thickness of dielectric materials. One has a permittivity four
times that of empty space. The other has twelve times that of empty
space. The capacitor is charged to 120 V...

Describe the relationship between the effective capacitance for
a series and parallel combination to the individual capacitance of
each capacitor. Derive the equations.

Q1)The Miller effect
can be described as....
A)
An effect by which a
capacitor connected at the input of a high-gain amplifier appears
reflected at the output of the amplifier divided by the gain.
B)
An effect by which a
capacitor connected at the output of a high-gain amplifier appears
reflected at the input of the amplifier multiplied by the gain.
C)
An effect by which a
capacitor connected in the feedback path of a high-gain amplifier
appears reflected at...

For a BJT amplifier where the collector is used as the output,
it is usually a good idea to bias the collector at the same voltage
as the base in order to get a symmetric output voltage swing. True
or False? Explain why.

Derive the photo electric effect.
a) include drawing of in energy levels of conductors
b) make equation of drawing
