Abstract
An image sensor, a level shifter circuit, and an operation method thereof are provided. The image sensor includes a pixel circuit and a pixel driving circuit. The pixel driving circuit includes first, second, third, fourth, fifth, and sixth transistors. A first terminal of the first transistor is coupled to a first voltage. A first terminal of the second transistor is coupled to the first voltage, and a control terminal of the second transistor is coupled to a control terminal of the first transistor and a second terminal of the first transistor. A first terminal of the third transistor is coupled to the second terminal of the first transistor, and a second terminal of the third transistor is coupled to a ground voltage. A first terminal of the fourth transistor is coupled to a second terminal of the second transistor and an output terminal.
