Abstract: An image sensor includes: a pixel array including a plurality of pixels, wherein each of the pixels includes first and second photodiodes, first and second transfer gates, and a plurality of active regions; and a logic circuit. Each of a plurality of pixel groups in the pixel array includes a first pixel and a second pixel. The active regions in each of the first pixel and the second pixel include a first active region and a second active region. The first active region is adjacent to the first transfer gate. The second active region is adjacent to the second transfer gate. In each of the pixel groups, a plurality of source-follower transistors respectively has a gate connected to the first and second active regions of the first pixel and connected to the first and second active regions of the second pixel. The source-follower transistors are in the first pixel.

Abstract: A system to transmit and receive wireless power, a terminal device, a management server, and a wireless power transmission apparatus may use non-radial wireless energy transmission technology to generate a resonant frequency in resonators and charge a device. The terminal device may receive the wireless power to perform charging by non-contact energy transmission.
