1. Read Chapter 11 section 3 in the text.
  2. Read Op Amp Oscillator Circuits.pdf
  3. Answer the following questions:
  • List the general requirements for oscillation
  • How does an RC combination affect the phase plot of an oscillator
  • For a Wien-bridge oscillator
    1. Given R = 20Kohm and C = 10nF what is the frequency of oscillation?
    2. Given a required frequency of oscillation of f = 3kHz and R = 5kohm, what should the value of C be?
