Abstract

　本発明は、スイッチング素子としてＮチャネル形トランジスタのみを使用する構成であっても閾値落ちが生じないチャージポンプ方式の昇圧部を含む電源回路を提供することを目的とする。昇圧部（１１ａ）においてコンデンサ（Ｃ１）および（Ｃ２）の一端にそれぞれ接続されるトランジスタ（Ｑ１，Ｑ３）および（Ｑ２，Ｑ４）の各ゲート端子に与えるべき制御信号を駆動部（１１ｂ）で生成する。駆動部（１１ｂ）のコンデンサ（Ｃ３，Ｃ４）に接続される入力端子（Ｔｉ３，Ｔｉ４）に、上記コンデンサ（Ｃ１，Ｃ２）の他端に与えられるクロック信号ＤＣＫ１，ＤＣＫ１Ｂをレベルシフトさせた信号として、－ＶＤＤとＶＤＤとの間で交互に電圧の変化するクロック信号ＤＣＫ２，ＤＣＫ２Ｂを与える（ＶＤＤは外部からの入力電源電圧）。これにより駆動部１１ｂは、ＶＤＤと３ＶＤＤとの間で交互に電圧の変化する信号を上記制御信号として生成する。
