Title:
チャージポンプ回路及び昇圧回路
Document Type and Number:
Japanese Patent JP6817053
Kind Code:
B2
Abstract:
A charge pump circuit includes a first capacitor and a second capacitor to which respective pulse signals are input; a first transistor including a source connected to a voltage input terminal, a drain connected to the first capacitor and a gate connected to the second capacitor; a second transistor including a source connected to the voltage input terminal, a drain connected to the second capacitor and a gate connected to the first capacitor; and a potential fixing circuit provided between a first node that is a connection node of the first transistor and the first capacitor, and a second node that is a connection node of the second transistor and the second capacitor. The potential fixing circuit fixes a potential of the first node to a potential according to a potential of the second node.
