It is assumed that the student has had some background in transistor amplifier theory, including the use of ac equivalent circuits.


The student is expected to develop his or her own procedure for performing the lab experiment, after having done a complete prelab analysis, and then analyze, and thoughtfully summarize, ce amplifier experiment results of the experiment in a lab report.

What are the various types of biasing a Transistor? What is Q point of operation of the transistor? Ce amplifier experiment is the region of operation of the transistor when it is working as an amplifier?

Common Emitter Amplifier Experiment

If these are reasonably close to your predictions, connect the ac input signal to the input of the amplifier. Use DC c oupling and dual-trace on the oscilloscope, as appropriate, to observe the waveforms at various points.

Is ce amplifier experiment output signal Vo close to expected? What kind of wavef orm, if any, is seen at test point B?


By changing the source and drain resistors, it may be possible to further optimize the amplifier for a larger peak output signal.

In ce amplifier experiment, by using Electronics Workbench, note how easy it is to interactively change any component at will, and immediately see the effects, which further stimulates, encourages, and enhances the learning process. We changed these parameters to: More information on these JFET parameters can be found in the Electronics Workbench and Pspice reference books, and in ce amplifier experiment last reference cited at the end of this a rticle.

Its Re ce amplifier experiment called the transresistance, which is calculated as: We can calculate the gain as thus: Ce amplifier experiment, the transresistance can be unstable in the transistor, so we need to add our own R in addition to the transresistance.

Scherz recommends a Ve of 1 V to stabilize the transresistance instability, so via Ohm's law: But note that that adding this R to the circuit: What is the importance of gain bandwidth product?

Draw h parameter equivalent circuit of CE amplifier. What is the importance of coupling capacitors in CE amplifier? Recall that Zi ce amplifier experiment across the input of the amplifier, and Zo appears in series with the output of the amplifier's dependent voltage source.

Refer to this equivalent circuit for the procedures that follow. You may hear a very faint response, but it will be buried in the noise.

Let's amplify the spikes some more.
