a) Design an oscillator that operates at a frequency of 200 MHz with the
following specifications:
Inductance: 15 nH
Q factor: 50,
Transistor transconductance with $g_m = 20$ mS
$R_o = 1/G_o = 100 \Omega$.
$g_m = 0.020$
$G_o = \frac{1}{100} = 0.01$
b) For 10% tolerance in inductor, determine the lowest value required for the Q
factor of inductor.
$|2 -4| = 2(3) - (-5)(1-9)$
