| 摘要 |
This invention discloses a decoupling capacitor in an integrated circuit, comprising a plurality of dedicated PN diodes with a total junction area greater than one tenth of a total active area of functional devices for which the dedicated PN diodes are intended to protect, a N-type region of the dedicated PN diodes coupling to a positive supply voltage (Vdd), and a P-type region of the dedicated PN diodes coupling to a complimentary lower supply voltage (Vss), wherein the dedicated PN diodes are reversely biased.
