Abstract
Description
Demux回路内のスイッチのオン/オフ状態を制御するための信号をスイッチ信号として設定することと、スイッチ信号の各立ち上がり期間を2つのフェーズに分割することとを含み、Demux回路のスイッチは、スイッチ信号の立ち上がり期間中、オン状態を維持する。
駆動モジュールは、Demux回路モジュール内のスイッチのオン/オフ状態を制御するためのスイッチ信号をDemux回路モジュールに出力し、スイッチ信号が立ち上がる各立ち上がり期間は、2つのフェーズに分割され、Demux回路モジュール内のスイッチは、スイッチ信号の立ち上がり期間中、オン状態を維持する。
Demux回路内のスイッチのオン/オフ状態を制御するための信号をスイッチ信号として設定することと、スイッチ信号の各立ち上がり期間を2つのフェーズに分割することとを含み、Demux回路のスイッチは、スイッチ信号の立ち上がり期間中、オン状態を維持する。ここで、スイッチ信号の立ち上がり期間とは、スイッチ信号が高電気レベルから低電気レベルに変化し、再び高電気レベルに変化するまでの期間である。2つのフェーズは、第1のフェーズと第2のフェーズを含む。第1のフェーズTが終了すると、スイッチ信号は、低電気レベルから所定の電気レベルに変化し、ここで、所定のレベルは、低電気レベルと高電気レベルとの間の電気レベルである。更に、スイッチ信号が所定の電気レベルであるとき、スイッチは、オン状態を維持する。第2のフェーズT1が終了すると、スイッチ信号は、所定の電気レベルから高電気レベルに変化する。第1のフェーズTと第2のフェーズT1を合わせた期間が立ち上がり期間となる。
