Summary:To provide a decoupling capacitance (Decap) system using a thin gate oxide film.SOLUTION: A decoupling capacitance (Decap) system 208A includes a Decap circuit 210 electrically connected between a first reference voltage rail 214 or a second reference voltage rail 216 and a first node, and a bias circuit 212 connected between an internal node 218 and the corresponding second or first reference voltage rail. Due to the connection of the Decap circuit and the bias circuit in series, the voltage drop V_bs of the bias circuit effectively reduces the voltage drop V_dcp of the Decap circuit, and the voltage drop of the Decap circuit becomes smaller than the voltage drop VDD of the Decap system.SELECTED DRAWING: Figure 2A 【課題】薄いゲート酸化膜を用いたデカップリングキャパシタンス(Decap)システムを提供する。【解決手段】デカップリングキャパシタンス(Decap)システム208Aは、第1基準電圧レール214又は第2の基準電圧レール216と第1のノードとの間に電気接続されたDecap回路210と、内部のノード218と対応の第2の基準電圧レール又は第1の基準電圧レールとの間に接続されたバイアス回路212と、を備える。Decap回路とバイアス回路が直列接続されることにより、バイアス回路の電圧降下V_bsがDecap回路の電圧降下V_dcpを効果的に低減して、Decap回路の電圧降下をDecapシステムの電圧降下VDDよりも小さくさせる。【選択図】図2A
