Abstract: A pixel for an ambient light and/or color sensor includes a plurality of pinned photodiodes. The pixel also includes a floating diffusion region. A ratio of an active area of the plurality of pinned photodiodes to an area of the floating diffusion region is greater than 150.

Abstract: A single wavelength fiber-optic communication system that mixes an Ethernet signal with a radio frequency signal is disclosed. The system includes an Ethernet signal module, a radio frequency signal module, a mixer module and a receiver module. The Ethernet signal module provides an Ethernet signal. The radio frequency signal module provides a radio frequency signal. The mixer module provides an optical mixed signal by means of mixing the Ethernet signal with the radio signal at a single wavelength. The receiver module transforms the optical mixed signal into the radio frequency signal and a digital signal that contains the Ethernet signal.

Abstract: The present invention improves a frequency divider circuit so that the frequency divider further obtains a capability of operating an injection-locking frequency division without changing or adding any component; and, the frequency divider operates under low voltage and low power consumption yet in high frequency, where the present invention can be use in related fields of radio frequency and optoelectronic communication.

Abstract: The present invention is an optical fiber system and method for carrying both CATV and Ethernet signals. The digital signals are translated into higher band by a direct up/down conversion so that analog signals and digital signals are treated as different frequency bands of electrical signals. Then, all the signals are mixed/divided by a power combiner/divider. And then, by using optoelectronic devices, the signals are processed with optoelectronic conversion. The converted optical signals are transmitted in a fiber or a related optical channel having low channel loss yet high capacity. To sum up, the present invention can transmit digital signals together with analog signals in a single wavelength to save the cost of an optical signal system and to provide a convenience on rearranging the system.
