Summary:To provide a clock wave peak value boost circuit capable of operating at a low voltage.SOLUTION: In a clock wave peak value boost circuit 100, a depletion type NMOS transistor 101 is so configured that a source is connected to a node N11, a drain is connected to a power supply terminal 1, and a gate is connected to an input terminal 10. An NMOS transistor 102 is so configured that a source is connected to a GND terminal 2, a drain is connected to a node N11, and a gate is connected to an input terminal 11. A depletion type NMOS transistor 104 is so configured that a source is connected to a node N12, a drain is connected to the power supply terminal 1, and a gate is connected to the input terminal 11. A capacitor 103 is connected between the nodes N11 and the nodes N12. A PMOS transistor 105 is so configured that a source is connected to the node N12, a drain is connected to the output terminal 12, and a gate is connected to the input terminal 11.SELECTED DRAWING: Figure 1 【課題】低い電圧で動作が可能なクロック波高値ブースト回路を提供する。【解決手段】クロック波高値ブースト回路100において、ディプレッション型NMOSトランジスタ101は、ソースがノードN11に接続され、ドレインが電源端子1に接続され、ゲートが入力端子10に接続されている。NMOSトランジスタ102は、ソースがGND端子2に接続され、ドレインがノードN11に接続され、ゲートが入力端子11に接続されている。ディプレッション型NMOSトランジスタ104は、ソースがノードN12に接続され、ドレインが電源端子1に接続され、ゲートが入力端子11に接続されている。コンデンサ103は、ノードN11とノードN12の間に接続されている。PMOSトランジスタ105は、ソースがノードN12に接続され、ドレインが出力端子12に接続され、ゲートが入力端子11に接続されている。【選択図】図1
