Abstract:
1. A switching circuit comprising: a first well and a second well configured to be formed in a semiconductor substrate; a first transistor configured to be connected with a first node at one end of the first transistor, and the first transistor being formed in the first well; a second transistor configured to be connected with another end of the first transistor at one end of the second transistor, and connected with a second node at another end of the second transistor, and the second transistor being formed in the second well; and a potential control circuit configured to switch connection of the second well from the second node to the first node during a predetermined period including a period for the first transistor and the second transistor to transition from off to on in a state where a potential of the second node is lower than a potential of the first node, and to switch the connection of the second well from the first node to the second node after the predetermined period.
