Can you be a bit more specific re: transistor material covered on the midterm?..
Content Questions
How can
be zero if
? Doesn't
imply the current is only zero when the voltage is?
What is
exactly? Is it the sum of
and
? Can it be freely controlled assuming control of
and
?
What exactly does the saturation region mean in terms of the physical charge distribution of the pnp/npn junction? Same for ON state.
How do we make use of the saturation region? How would it be applied in a problem?
How exactly does the switch work in a practical way? What is switching on under which conditions?
What are some examples of applications of ``transistor as switch''?
What is the input impedance?
To what extent do we need to know the details of the transistor approximations for the small signal models?
