ACOUSTIC NOISE CANCELLATION IN MULTI-LAYER CAPACITORS

摘要

A device is presented for decoupling voltage transients occurring on a voltage signal generated by a voltage regulator. The dev ice may decouple the voltage transients from circuits coupled to the voltage regulator. The device may include two capacitors that may be contained in a single package. The two capacitors may be coupled to the voltage signal from the voltage regulator such that one capacitor is also coupled to a ground reference and the other capacitor is also coupled to a supply voltage. The capacitors may be constructed in a multi-layer ceramic capacitor (MLCC) process. The materials that form the MLCC may be arranged such that the MLCC package does not change shape or vibrate in response to voltage level fluctuations on the voltage signal.
