reducing the non linearity in ringoscillator based vco

[arya.jagadeesh]

i am trying to design vco with ring oscillator ..variation of output frequency with control voltage is not linear......is there any way to decrease the nonlinearity

You can post your design...... you are using not gates or Mosfets.....

try this link stable Ring oscillator

nonlinarity

i have used differential pairs .....

I guess you want to repeat the simulation with a reasonable number of points. Let's see if there's actually nonlinearity or just saturation.

if i am plotting the outputs of counter individually they are plotted...instead i want to plot the value like say for 3 bit 000 001 010...etc what to do
