PLL Phase Locked Loop Gain
- the phase locked loop needs to remain stable under all operating conditions. To achieve this, the loop gains and filter points must be calculated to ensure loop stability is always maintained.
One of the key aspects of a phase locked loop is its stability. This is controlled by the loop response and the loop gain.
These two factors are linked, and one of the main configurables that enables the loop stability to be controlled is the loop filter performance..
While elements such as the gain of the various elements: VCO, phase detector, etc are important, it may not be easy to change their performance.
