How can I make pss simulation converge?
I want to see the phase noise of Current Controlled Oscillator(Ring Oscillator) output with those choppers.
At first, I tried to do simulation with oscillator blank checked. And then I figured that there should be no other fundamental frequencies with oscillator setting.
So, I unchecked oscillator setting, and then I set my settings shown above.
The CCO output frequency is approximately 1.036MHz.
So, I set beat frequency as 1kHz(GCD) but it failed to converge.
Could you give me any suggestions?
