Abstract
This technology relates a unit pixel and an operating method thereof and a CMOS image sensor using the same. The unit pixel may include a photo sensitive device; a reset transistor; a selection transistor including a gate terminal, a first terminal and a second terminal, suitable for operating in response to a selection control signal applied to the gate terminal and outputting a voltage applied to the first terminal to a first terminal of the reset transistor through the second terminal; and a drive transistor including a first terminal coupled to the second terminal of the selection transistor, a second terminal and a gate terminal, suitable for generating an electrical signal corresponding to charges accumulated in a floating diffusion node coupled to the gate terminal, and outputting the electrical signal as a pixel signal through the second terminal.
