Design a Colpitts oscillator operating at 200 MHz using an FET
in a common gate configuration, including the effect of a lossy
inductor.
5.1. Derive equations for the resonant frequency and conditions
required for sustaining oscillation, for an inductor with loss.
(Hint: Use with the matrix given below) � (𝑌1 + 𝑌2 + 𝑔𝑚 + 𝐺0)
−(𝑌2 + 𝐺0) −(𝐺0 + 𝑔𝑚 + 𝑌𝑌2) (𝑌1 + 𝑌2 + 𝐺0) = 0 [9]
