Electronics 1 (Devices and Materials), Single-Transistor Amplifier

Design a single-transistor amplifier to supply a load of 1k? from a signal source with a resistance of 10k?,
using a power supply of 5V. The minimum performance requirement is that your amplifier have a power gain of
at least 10 (10dB). This means that the amplifier must deliver at least ten times as much power to the load as it
draws from the source. You are allowed to use a BJT or a MOSFET, as well as any amplifier configuration of
your choosing. You should use one of the “good” biasing arrangements given in the chapter.
A SPICE template file has already been created for you and is available for download from Blackboard. It
contains the power supply, input section, output section, the model statements for the two transistor options, and
the analysis commands. Follow the instructions given in the file and add the rest of your circuit to make it
complete. Use the instructions and analysis commands given to evaluate your amplifier. See the last page of this
document for a schematic representation of the template given.
If you meet the performance requirement of a 10dB power gain, full credit will be given for the performance. In
addition, a competition will be held for bonus points. Bonus points will be awarded to the top performers in the
following categories:
? Overall voltage gain (5 points)
? Highest input resistance (5 points)
? Lowest output resistance (5 points)
? Lowest DC power consumption (5 points)
Achieving the number one performance in one of these categories will add the given number of points to your
final grade for the course. The top fifteen performers in each category will receive bonus points, scaled by rank.
Ties will have the points divided up between them. You can receive points from more than one category.
Any submission will be disqualified that changes the source resistance, load resistance, supply voltage,
transistor model statements, or uses more than one transistor.
