Abstract :
The impedance of a microprocessor power-delivery network peaks at ~140MHz, resulting in power-grid resonance, which lowers operating frequency and compromises reliability. A suppression circuit uses an active-damping technique with a maximum of 12.7dB peak-to-peak noise reduction from 70 to 250MHz in a 90nm CMOS process.
