Effect of bypass capacitance
Webbus), as little as 1nH bypass series inductance can cause noise on the supply that violates the low side of 3.3V +0.3V/-0.165V supply specification. Changing the size of bypass capacitance has little effect on changing the peaking of this noise since the series inductance of the bypass capacitor dominate s the effective impedance across the capac- WebNov 6, 2024 · This is because: 1The capacitor lead inductance generates capacitor resonance, which causes high-frequency signals to have a large impedance and weakens the bypass effect; 2The parasitic capacitance between the wires causes the high …
