    摘要： A phase locked loop design that uses a switch operatively connected to a loop filter capacitor to control a leakage current of the loop filter capacitor is provided. By positioning a switch in series with the loop filter capacitor, the leakage current of the loop filter capacitor may be controlled by switching the switch ‘on’ when a charge pump of the phase locked loop is ‘on’ and switching the switch ‘off’ when the charge pump is ‘off,’ thereby cumulatively reducing the leakage current of the loop filter capacitor throughput the operation of the phase locked loop. Control and reduction of the loop filter capacitor leakage current leads to more reliable and stable phase locked loop behavior.

    摘要： A method and apparatus for post-fabrication adjustment of a phased locked loop leakage current is provided. The adjustment system includes a programmable current source that adjusts a leakage current offset circuit to compensate for the leakage current of a capacitor. The capacitor connects to a control voltage of the phase locked loop. The programmable current source includes at least one current source and switch to adjust the leakage current offset circuit. The programmable current source is selectively adjusted by a combinational logic circuit. Such control of the leakage current in the phased locked loop allows a designer to achieve a desired phase locked loop operating characteristic after fabrication of the adjustable phase locked loop.

The calibration and adjustment system includes an adjustment device that varies an amount of charge pump current. Such control of the charge pump current in a delay locked loop allows a designer to achieve a desired delay locked loop operating characteristic after the delay locked loop has been fabricated. A representative value of the amount of adjustment desired in the charge pump current may be stored and subsequently read to adjust the delay locked loop.

    摘要： A calibration and adjustment system for post-fabrication control of a delay locked loop bias-generator is provided. The calibration and adjustment system includes an adjustment circuit operatively connected to the bias-generator, where the adjustment circuit is controllable to facilitate a modification of a voltage output by the bias-generator. Such control of the voltage output by the bias-generator allows a designer to achieve a desired delay locked loop performance characteristic after the delay locked loop has been fabricated. A representative value of the amount of adjustment desired in the bias-generator output may be stored and subsequently read to adjust the delay locked loop.
