thank you for your replying,biff44.
i found the error of my thought.Indeed,the maximum single-end output range is from 0 to 2VDD rather than 0 to VDD.
in my previous calculation ,i use the drain current of the differential-coupled pair multiply Rp to calculate the output voltage.
The current is...
Dear guys:
I am confused that some pappers say the maximum output of the vco is 2VDD.
the vco ,e.g with nmos or complementary differential-couple LC oscillator operated in voltage-limitted region , the maximum differential output of it is from -VDD to + VDD,thus the maximum differential...
Thinks alot
But I donot clear about why V-=Vx - Vy instead of V-=0
Added after 11 minutes:
I guess in the file the Vo/Vi means modulus
neglect the phase
The application report says R3=(Vo/Vi)/(2-2Vo/Vi),but I calculate R3=-(Vo/Vin)/（2Vo/Vin+2)

Some books says that the 3db points from the top are pole but some times they say the top is at pole point,why,
