1. Lab goals
 Topics


Transistor smallsignal model parameters and smallsignal circuit analysis.

Prediction and measurement of amplifier input resistance, voltage gain, and output resistance.

2. DC solution

Calculate the DC values of all node voltages and collector currents in the CB + EF Amplifier circuit.

Build the circuit and measure the node voltages ("Ohm’s law" the collector currents) to verify that you have both done the calculations correctly and have a functioning amplifier.
3. AC circuit performance
3.1. Measurements
Set the signal generator to an ampliitude of 20 mVpp at 1 kHz. The 50 Ω resistor is inside the generator and is its Theveninequivalent output resistance.

Measure the voltage gain of the amplifier v_{out} / v_{in}.
Use the concepts of equivalent input and output resistance to make a strategy to measure the amplifier’s R_{in} and R_{out} as shown in CB + EF Amplifier.

Measure the amplifier’s R_{in} and R_{out} using your technique.
3.2. Predictions
Redraw the schematic as a cascade of two general voltagein / voltageout amplifiers. (see the whiteboard figure) Use this structure and your DC bias solutions to calculate each subamplifier’s input resistance, output resistance, and voltage gain.
See the Guidebook [bjtamplifiers#_tables_and_terminology^].
From those numbers, predict the composite amplifier’s R_{in}, R_{out}, and voltage gain. This should include the effects of the signal generator’s output resistance and the load resistance.
