	%X This paper proposes for the first time symbolic
formula of the power spectrum of CMOS Cross Couple Oscillator
and its modified circuit. Many principles existed to derived power
spectrum in microwave textbook such as impedance, admittance
parameters, ABCD, H parameters, etc. It can be compared by graph
of power spectrum which methodology is the best from the point of
view of practical measurement setup such as condition of impedance
parameter which used superposition of current to derived (its current
injection at the other port of the circuit is zero, which is impossible in
reality). Four graphs of impedance parameters of cross couple
oscillator are proposed. After that four graphs of scattering
parameters of CMOS cross coupled oscillator will be shown.
