Adjustment and calibration system for post-fabrication treatment of phase locked loop charge pump

摘要

An adjustment and calibration system for post-fabrication treatment of a phase locked loop charge pump is provided. The adjustment and calibration system includes at least one adjustment circuit, to which a phase locked loop charge pump output is responsive, and a storage device that selectively stores control information (1) associated with a state of the adjustment circuit and/or (2) from a tester that writes such control information to the storage device, where the control information stored in the storage device is subsequently selectively read out in order to adjust the adjustment circuit to a state corresponding to the control information.
