Description
従来の負帰還増幅回路500は、ソース接地増幅回路の増幅回路510と、増幅回路520とから成る。増幅回路510は、直列に接続された電流源511とNMOSトランジスタ512から成る。
増幅回路510の出力は、増幅回路520の入力に接続される。増幅回路520の出力は、増幅回路510のNMOSトランジスタ512のゲートに接続される。
また、その増幅回路を備えたボルテージレギュレータとした。
図1の、本実施形態の増幅回路110は、電流源111と、NMOSトランジスタ112及び113と、容量114と、を備えている。
NMOSトランジスタ112のゲートには、増幅回路110の入力電圧である電圧V2が与えられる。NMOSトランジスタ112のゲート・ソース間電圧は、電圧V2に同期した電圧となるため、NMOSトランジスタ112は電圧V2に応じた電流を流す。
ボルテージレギュレータ100は、図1に示した増幅回路110と、増幅回路120と、出力端子101と、を備える。増幅回路120は、NMOSトランジスタ121と、抵抗122と、抵抗123と、を備える。
増幅回路120は、入力された電圧V1aに基づいて増幅動作が成され、増幅した電圧VOUTを出力する。また、増幅回路120は、電圧VOUTを抵抗122及び抵抗123で分圧して帰還電圧である電圧V2を増幅回路110の入力端子に出力する。従って、増幅回路110と増幅回路120とは、互いに入力端子と出力端子とが接続されているため、負帰還増幅回路を構成している。電圧VOUTが低くなると、即ち帰還電圧である電圧V2が低くなると、増幅回路110は、NMOSトランジスタ112及び113がオフしていくので、出力する電圧V1aは高くなる。増幅回路120は、NMOSトランジスタ121がオンしていくので、出力する電圧VOUTは高くなる。また、電圧VOUTが高くなると、即ち帰還電圧である電圧V2が高くなると、増幅回路110は、NMOSトランジスタ112及び113をオンしていくので、出力する電圧V1aは低くなる。増幅回路120は、NMOSトランジスタ121がオフしていくので、出力する電圧VOUTは低くなる。即ち、ボルテージレギュレータ100は、電圧VOUTが一定に保たれるように動作する。
なお、ボルテージレギュレータ100は、増幅回路110を、上述したように、例えば増幅回路210のような回路構成としても、同様の効果が得られる。
ボルテージレギュレータ200は、増幅回路110と、増幅回路130と、増幅回路140と、出力端子101と、を備える。
増幅回路130は、NMOSトランジスタ131と、抵抗132を備える。増幅回路140は、PMOSトランジスタ141と、抵抗142と、抵抗143と、を備える。
このように構成したボルテージレギュレータ200は、ボルテージレギュレータ100と同様に負帰還増幅回路を構成するので、同様の効果が得られることは自明である。
