CPU Power Delivery Impedance Profile Resonances Impact on Core FMAX

CPU core FMAX dependence on power delivery impedance profile resonances is investigated. Repetitive on/off stimulus degrades FMAX more than a step di/dt stimulus. Multiple resonances may have an additive effect on power supply voltage drops
