Imaging element and electronic device

An imaging element, comprising:

• an analog circuit unit including a pixel that performs photoelectric conversion;
• a logic circuit unit configured to process a signal read out from the pixel;
• and
• a body potential generation unit configured to apply a body potential in a direction of lowering a threshold voltage to a well doped to enclose a transistor structure in a transistor forming the logic circuit unit.

An electronic device, comprising:

• an imaging element;
• and
• an operation mode designation unit configured to designate an operation mode for the imaging element, wherein
• the imaging element includes:
• an analog circuit unit including a pixel that performs photoelectric conversion;
• a logic circuit unit configured to process a signal read out from the pixel;
• a body potential generation unit configured to apply a body potential in a direction of lowering a threshold voltage to a well doped to enclose a transistor structure in a transistor forming the logic circuit unit;
• and
• a control unit configured to control the body potential for each operation mode designated by the operation mode designation unit.
