Oscillator Circuits HW

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?
