Abstract: An image sensor includes a pixel array including a first shared pixel and a second shared pixel that are adjacent to each other in a row direction. The first shared pixel includes two or more photo diodes in a first row and two or more photo diodes in a second row, and the first shared pixel includes a first floating diffusion region shared by the photo diodes of the first shared pixel. The second shared pixel includes two or more photo diodes in the first row and two or more photo diodes in the second row, and the second shared pixel includes a second floating diffusion region shared by the photo diodes of the second shared pixel.

Abstract: A method of operating an image sensor includes generating a plurality of sub pixel signals using a sub pixel group. The sub pixel group includes a plurality of sub pixels and corresponds to a single pixel. The method further includes generating a pixel signal having a plurality of bits based on a result of comparing the sub pixel signals with a reference voltage. Each of the sub pixels is a 1-transistor (1T) pixel that detects at least one photogenerated charge and includes only one transistor.

Abstract: An optical biosensor may include a biosensing unit, detection unit, and signal processing unit. The biosensing unit may be configured for receiving first and second optical signals (which are generated from a phase-modulated optical signal), outputting a sensing signal by transmitting the first optical signal via a first optical path that includes a sensing resonator, and outputting a reference signal by transmitting the second optical signal via a second optical path that includes a reference resonator. The detection unit may be configured for receiving the sensing signal and the reference signal, detecting a phase element of each of the sensing signal and the reference signal through a signal demodulation operation, and detecting a phase difference between the sensing signal and the reference signal according to the detected phase elements. The signal processing unit may be configured for calculating the concentration of a bio-material based on the detected phase difference.
