Using Op-Amps for Radio Frequency Design

The purpose of this lab is to construct a practical Colpitts RF Oscillator circuit with MultiSIM. The frequency of output waveforms will be measured using a virtual oscilloscope. Students will gain an appreciation for the effect biasing resistors have on the output frequency of an oscillator.

1. Construct the Colpitts Oscillator in Figure 2 in the document Week 4 – RF Oscillator.pdf with MultiSIM
2. Using the values of RG from the homework capture screenshots of the output waveform Vout for each case.
3. Measure the frequency of the output waveforms
4. Paste screenshots of measurements into a Word document entitled “Lab4_StudentID”.
5. Upload file “Lab4_StudentID”
