BJT's

100

Compared to MOSFETs, BJTs can drive this more of "this" between the collector and emitter compared to a mosfet's Drain to source.

What is more current?

200

Unlike the the mosfet, in order to bias the BJT, we must avoid using this method because BJTs are not voltage driven.

what is node voltage method.

300

The new name for Cutoff, linear and Saturation.

What is Cutoff saturation and active?

400

Daily Double: Draw the small signal model of a BJT under Bias.

Look it up, I'm not spending the $20 on pasting an image here.

500

Draw and Label the structure of a PNP transistor.

Look it up buddy.

Amplifiers

100

In the lab, this amplifier worked as the best start to a multistage amplifier.

What is a Differential Amplifier.

200

This is the draw back of using the "common" type of amplifiers.

What is lack of gain?

300

Daily double: Draw the small signal model of a SIMPLE current mirror.

Find it online bruh.

400

Derive the operating equations of a simple mosfet current mirror. (just Id1 is fine)

Id1 = (beta*(Vgs-vt)^2)*0.5;

Or 

Id1 = (Beta1/Beta2)*Ibias;

500

Draw the Small signal circuit for a multistage amplifier (Section B).

Scroll to section B and compare.

Datasheets

100

The Unit for this variable is Amps per Volts^2

What is Beta

200

Indicated in parenthesis by the variables, (ON) can tell us that the mosfet is definitely NOT in this mode.

What is Cutoff?

300

The maximum power can be calculated this way on a mosfet.

What is V*I, but it can't go over Maximum P. 

OR 

Vmax*someI

OR

SomeV*MaxI

400

This variable on the datasheet has a range and can determine whether or not the mosfet is conducting.

What is Vt?

500

Applying too much Voltage across the drain source makes the mosfet go in this region.

What is breakdown. 

Bonus if you can figure out if it is due to the diode or the D channel.

"You should Know how to do this"

100

____ does not depend on Vbc

____does depend on Vbe

What is Ic?

200

In an IC Amplifier, we should avoid these two components in our design.

What is resistors and capacitors.

300

The unit for forward transconductance.

What is Siemens.

400

This is the vertical duplication of a circuit, in our notes it is specifically used with a current mirror.

What is Cascoding.

500

Draw the small scale model of a Differential Amplifier.

Look up in notes.

Anything can happen

100

These type of datasheets do not include as much information compared to their originals.

What are new datasheets.

200

This is the Vt to a BS250 Pmos transistor.

what is -1 to -2.4

300

This is the Drain Source Breakdown Voltage of a BS250 pmos mosfet.

What is between -70 -60

400

This is the difference between the small signal model of a mosfet and BJT.

What is the inclusion of r sub pi? or Vbe?

500

When your Vc>Vb and Ve>Vb you are in this region of a BJT.

What is Active mode?
