Consider the oscillator circuit shown in the figure. The function of the network (shown in dotted lines) consisting of the 100 k $$\Omega$$ resistor in series with the two diodes connected back- to is to: GATE ECE 2016 Set 1 Analog Circuits - Oscillators Question 8 English
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 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
