| Popis: | The impedance of a microprocessor power-delivery network peaks at ~140 MHz, resulting in power-grid resonance, which lowers operating frequency and compromises gate oxide integrity. A suppression circuit is designed using an active-damping technique with a maximum of 13 dB supply voltage noise reduction from 70 to 250 MHz in a 90 nm CMOS process. |
