Due Monday 20180219 at the end of class.
1. Reading
Read / review [AoE] section 2.3 up until section 2.3.8 Differential amplifiers (our next topic).
Here are some notes on how the content of that section maps to our current course location:

Earlier, in section 2.2.9, is the concept of transconductance.

Section 2.3.2 starts with some ratio rules. Since they are at the page break, they are easy to miss, but are important for quickly understanding a circuit. BJT Rules of thumb has more discussion of these. Here are some (notice the capitalization means DC values):

\(\dfrac{I_{C2}}{I_{C1}} = \exp\left(\dfrac{\Delta V_{BE}}{V_T}\right)\)

\(\Delta V_{BE} = V_T \ln\left( \dfrac{I_{C2}}{I_{C1}} \right)\)


If you were paying attention, the Lab 3B circuit demonstrated a large temperature dependence in the
Q3
collector current when addingL1
. Section 2.3.2.C speaks to this effect. 
Section 2.3.2.D (p. 92) is Early effect, modelled as \(r_o\) in the transistor smallsignal models.

The circuits of section 2.3.5 (p 96) should be familiar!

Section 2.3.6 about the perfect transistor may be interesting. Such a structure (or rather voltagein and currentout) is usually called an operational transconductance amplifier or OTA. They are quite common in analog integrated circuits (onchip), and not as common for circuitboard level electronics.
2. Study
Slowly read through the Minima microphone amplifier analysis from [341notes] that was started in class Wednesday.
It has complete worked solutions for the:

DC bias solution

Smallsignal voltage gain A_{v}

Smallsignal input impedance R_{in} and Z_{in}

Smallsignal output impedance R_{out} and Z_{out}
Most important is to make the connections between the fullon algebra and the table entries of [bjtamplifiers#bjtamplifiers].
3. Lab circuit analysis
Use Minima microphone amplifier analysis as your example of how your work should look in terms of neatness and format.
Clearly write out your mathematical circuit analysis of the following for your specific lab circuit and power supplies, in all cases, ignore \(r_o\) by replacing it with an open circuit:

DC bias solution. All node voltages and collector currents.

Amplifier input resistance, \(R_{in}\), not just the CE amplifier’s \(Z_{in}\) from the Table. (Lab 3A: with
Ce
but notL1
), (Lab 3B: withoutL1
) 
Amplifier voltage gain \(v_{out} / v_{in}\).

Estimate your amplifier’s output resistance \(R_{out}\), again not merely the CE amplifier’s \(Z_{out}\).
Turn in this work at the end of class on Monday.
