    摘要： First diffusion region constituting a photodiode in each pixel stores carriers generated according to incident light. Second diffusion region is formed at a surface of the first diffusion region to cover a peripheral part of the first diffusion region. In the peripheral part of the first diffusion region, crystal defects tend to occur by a process of forming an isolation region and a gate electrode, so that dark current noise tends to occur. The second diffusion region functioning as a protection layer prevents crystal defects in a manufacturing process. The second diffusion region isn't formed on a center of the surface of the first diffusion region where crystal defects don't tend to occur. In the first diffusion region where the second diffusion region isn't formed, the thickness of a depletion layer increases, which improves light detection sensitivity. This improves detection sensitivity of the photodiode without increasing the dark current noise.

    摘要： In measurement of wireless channels in an IEEE 802.11 wireless local area network (WLAN), in the case of multi-channel measurement as in North America in which eight wireless channels Ch1 through Ch8 are available, channel measurement according to a predetermined algorithm is made in which odd-numbered channels Ch1, Ch3, Ch5 and Ch7 are first measured, and if radio interference occurs in channel Ch5, channels Ch4 and Ch6 adjacent to channel Ch5 are measured. This shortens the measurement time that conventionally corresponds to measurement of the eight channels to the time of six channels, i.e., the sum of the measurement time for the odd-numbered channels and that for the channels adjacent to the interference-occurring channel.
