Abstract :
We have thoroughly investigated and experimentally demonstrated the great advantages of thin film embedded capacitors of high dielectric constant in reducing power/ground impedance and suppressing SSN and radiated emission up to a frequency of 1 GHz. About 10 dB or more suppression of the radiated emission was acquired for a wide frequency range, including high-numbered harmonics of the clock frequency, by using the thin film embedded capacitor of high dielectric constant.
