vco supply filter
What is the exact definition of PSRR for VCO? Is it the ratio of change of output frequency and the change of supply voltage?. In that case, the unit will be Hz/V.Is it right? How can you calculate in dBs? If some one answers, that would be fine.
psrr voltage controlled oscillator
Thanks for your response. I am little bit confused with the calculation of the jitter due to the ripples in the power supply. Can i run PSS and Pnoise analysis to measure that?
psrr pll
Actually i am giving a sine wave of 1MHz frequency with the DC voltage of 1.8V. The amplitude of the sine wave is +/- 50mV. How do i plot the frequency with respect to supply? Do i have to measure manually at 1.8+50mV 1.8V and 1.8-50mV?
