Consider the oscillator circuit shown in the figure. The function of the network (shown in dotted
lines) consisting of the 100 k? resistor in series with the two diodes connected back-to-back is to:
 
 
  • a)
    introduce amplitude stabilization by preventing the op-amp from saturating and thus producing sinusoidal oscillations of fixed amplitude
  • b)
    introduce amplitude stabilization by forcing the op-amp to swing between positive and
    negative saturation and thus producing square wave oscillations of fixed amplitude
  • c)
    introduce frequency stabilization by forcing the circuit to oscillate at a single frequency
  • d)
    enable the loop gain to take on a value that produces square wave oscillations
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Consider the oscillator circuit shown in the figure. The function of t...
The circuit shown is a wein bridge oscillator. The amplitude of oscillations can be determined and stabilized by using a nonlinear control network. As the oscillations grow, the diodes start to conduct causing the effective resistance in the feedback to decrease. Equilibrium will be reached at the output amplitude that causes the loop gain to be exactly unity.
