Title:
SYSTEM TO CONTROL INTEGRATED CIRCUIT RESONANCE
Document Type and Number:
WIPO Patent Application WO2004109888
Kind Code:
A3
Abstract:
According to some embodiments, a control signal is generated to reduce resonance of a circuit at an operation point, a characteristic of the control signal based on a proximity of an existing operation point to the operation point. Generation of the control signal may include sensing of a current associated with an input voltage signal, generation of a current-based signal based on the sensed current, and generation of the control signal based on a phase difference between the current-based signal and the input voltage signal.
