Determine the transfer function $$\left( {{{{V_y}} \over {{V_x}}}} \right)$$ for the $$RC$$ network shown in figure $$(1).$$ GATE EE 2002 Analog Electronics - Feedback Amplifiers and Oscillator Circuits Question 4 English 1 GATE EE 2002 Analog Electronics - Feedback Amplifiers and Oscillator Circuits Question 4 English 2

The network is used as a feedback circuit in an oscillator circuit shown in figure $$(2)$$ to generate sinusoidal oscillations. Assuming that the operational amplifier is ideal, determine the value of $${R_F}$$ for generating these oscillations. Also determine the oscillation frequency if $$R = 10\,\,k\Omega $$ and $$C=100PF$$
