Post-silicon control of phase locked loop charge pump current |
摘要 |
A post-silicon technique for adjusting a current of a charge pump in a phase locked loop is provided. The technique involves use of an adjustment circuit operatively connected to the charge pump, where the adjustment circuit is controllable to facilitate an internal biasing of the charge pump. Such control of the charge pump current in a phase locked loop allows a designer to achieve desired PLL performance characteristics after the PLL has been fabricated.
