Calculation of Oscillator Output Power [hlp]

Dear friends
I want to formulate output power a cross coupled oscillator. Do you know any book/paper/application note that describe it? Do you know about it?
tnx

Any time I've wanted to examine the steady-state output power/amplitude of something that oscillates I've been sucked straight down into the rabbit-hole of nonlinear analysis :) I'd be surprised if there was a simple analytic expression/description that applied to an architecture in general..?

Empirically, I've found Agilent's ADS "Harmonic Balance" frequency domain simulation tool to be pretty good for other oscillator architectures - you might be able to appropriately model your oscillator and extract some trends/design guidelines.

Output voltage is approximately

Vo=2/Itail*Rp*pi

Rp=Equivalent Resistance of LC Tank Circuit//Load Resistance
Itail=Bias current
