5. 6.20 For an OP-Amp phase shift oscillation, the frequency of oscillations is (a) 2 RC 2 RC./3 [ESE-2015]

6. 6 The oscillator circuit shown in ideal inverting amplifier. Its frequency of os (in Hz) is the figure has an cillation (D) (2tRC) (VeRC) [2003 2 Marks]

7. 6.7 An amplifier will generate stable sinusoidal oscillations if we provide feedback such that (a) its poles lie close to jo-axis in the right half of s-plane s-plane s-plane (b) its poles lie close to jo-axis in the left half of (c) its poles lie on the +ve real axis in pli awhere in s-plane [ESE-2002]

9. 6.10 Three amplifiers each of gain (A./2) and producing a phase of 60 are connected in tandem. The feedback loop is closed through a positive gain of 0.008. What should be the value of Ap for the system to be oscillatory? (a) +10 (c) +250 (b) -10 (d) +83.3 [ESE-2005]
