Abstract: The invention generally relates to phase locked loops (PLL), and more specifically to ultra-low bandwidth phase locked loops. The invention may be for example embodied in an integrated circuit implementing a phase locked loop or a method for operating a phase locked loop. The invention provides a PLL with a control stage that uses only two storage cells, a counter and a digital-to-analog (DAC) converter. In comparison to prior-art PLLs using storage cells the configuration of the invention's control stage reduces the chip area required for the PLL reduced. The invention further suggests PVT compensation mechanisms for a PLL and implementing a PLL that has lower peaking in its frequency response, which results in better settling response.
