Systems and methodologies are described that facilitate calibration of the loop bandwidth of a phase-locked loop (PLL). Calibration for the loop bandwidth of a PLL as described herein can be performed by optimizing the loop response of the PLL. Optimization of the loop response of the PLL can...
Introduction PLL bandwidthis used to calculate the feedback gain for the controller’s phase-locked loop, PLL:Pll KpandPll Ki. The PLL tracks the sensorless angular position of the motor for motor modelling flux frequency calculation. It controls the output frequency. AsPLL bandwidthincreases, the...
This example shows how to tune the components of a passive loop filter to improve the loop bandwidth of a phase-locked loop (PLL) system. To obtain a desired loop frequency response, this example computes the loop filter parameters using the fixed-structure tuning methods provided in the Contro...
The PLL bandwidth is determined by the loop filter's time constant, as well as the gains of the VCO, phase detector, and divider. The transient response, reference spurious level, and noise filtering properties are all determined by the PLL bandwidth. The phase noise on the frequency ...
An LC-VCO based phase-locked loop (PLL) frequency synthesizer which incorporates loop bandwidth tracking is described. In order to minimize loop bandwidth variations resulting from changes in the LC-VCO gain, the proposed PILL employs an averaging varact
