formula for phase noise calculation of amplifier
I don't know if there is a general, closed form formula for what you are asking.
If useful, phase noise is measured and included in a part's datasheet. For example, all of ADI's PLL/Synthesizer products include phase noise plots over various conditions.
Thanks for the reply.I want to to calculate the overall phase noise of the system, so for that i required phase noise value of the amplifier which is not included in the datasheet.
There is not a specific formula for calculating the phase noise of an RF amplifier. It really needs to be measured. For RF amplifiers, it is typically very low (-170 to -180 dBc/Hz). This makes it quite difficult to measure.
Have you any idea about calculation of total system (up conversion /down conversion)phase noise?
