What is the best method to simulate fractional-N synthesizers?
I would like to observe the shifts in average output frequency when I change the divide cycles of the programmable divider. I have attempted plotting the DFT of the output but this does not seem to be working because the output has...
Yes, the oscillator is to be used as a part of the synthesizer.
I am in fact using a MOS varactor that is non-linear.
Okay, I will add the bypass caps and buffers.
Thank you for taking the time to answer my query.
I actually require the higher frequency so adding stages does not seem to be an option.
I am using ideal sources in my simulation as of now so there should be no issue of external noises but I will keep this in mind for later.
Please can you...
I am trying to minimize the phase noise in a voltage-controlled ring oscillator circuit. I have a simple circuit consisting of CMOS inverters stages and a MOS varactor at each stage controlled by a control signal. How should I go about minimizing the phase noise in this circuit?
Any suggestions...
Hi everyone
I am trying to minimize the phase noise in a voltage-controlled ring oscillator circuit. I have a simple circuit consisting of CMOS inverters stages and a variable capacitance at each stage controlled by a control signal. How should I go about minimizing the phase noise in this circuit?
