    摘要： A phase locked loop design uses a diode operatively connected to a loop filter capacitor to control a leakage current of the loop filter capacitor. By positioning a diode in series with the loop filter capacitor, a voltage potential across the loop filter capacitor is reduced, thereby reducing the leakage current of the loop filter capacitor. Moreover, the leakage current of the loop filter capacitor is controlled in that it cannot exceed the current through the diode. Control and reduction of the loop filter capacitor leakage current leads to more reliable and stable phase locked loop behavior.

    摘要： A delay locked loop implementing design-for-test features to test for, among other, stuck-at-faults is provided. The delay locked loop uses multiplexers as design-for-test devices for controllability purposes and flip-flops as design-for-test devices for observability purposes. Such implementation of design-for-test features within a delay locked loop allows for pre-packaging delay locked loop verification and testing.
