Oscillator consist of a amplifier and a positive feedback network, positive feedback network consist of RC or LC network.

enter image description here

Vin = Vs + Vf

But Vf = BVo & A = $\frac{vG}{v_{in}}, v_in = \frac{vo}{17}$

$\frac{vo}{A} = vs + Bvo$

$\frac{vo}{A} - Bvo = Vs$

$V_o (\frac{1}{A}) - B_ = …
