Abstract
A loop filter for a phase-locked-loop is provided, comprising a set of capacitor banks coupled in parallel to form the loop filter, and a detection circuit for identifying and isolating defective capacitor banks. A method for providing a loop filter for a phase-locked-loop in accordance with an embodiment of the present invention includes the steps of forming the loop filter using a set of capacitor banks coupled in parallel, detecting any defective capacitor banks in the set of capacitor banks, isolating each defective capacitor bank, providing a set of redundant capacitor banks, and replacing each defective capacitor bank with a redundant capacitor bank from the set of redundant capacitor banks.
