Lab 8: Design Project


After completing seven series of experiments described in this manual you should have gained sufficient experience with analog and some digital circuits to venture into an exciting area of design and more independent work. With the approval of the instructor, the project ought to include at least two topic covered in past labs. For example, OpAm and a BJT amplifier. The students are encouraged to come up with a new design. The project should start with simulations of the circuit, which later will be compared with the result of experiments. A working circuit is mandatory.

Several examples are listed below: One such experiment may include the optional experiment at the end of Lab 1. A combination of analog and digital circuits, such as, amplifier with adjustable gain or a filter with adjustable bandwidth, in which parameters are changed by digitally controlled transmission gates (analog switches) is another example. Finally, a three stage amplifier with high input impedance achieved with an FET, a common emitter amplifier with a BJT (Lab 3) and a BJT voltage follower. The limits are set only by time and imagination.


Provide a brief description and a schematic of a circuit you plan to build. Describe also the expected circuit performance. Preferably, include simulations in the pre-lab report.


The format for the final report is the same as for earlier reports.
