Abstract: A relaxation oscillator includes a start-up circuit. During the start-up period of the relaxation oscillator, two output signals from the relaxation oscillator are controlled to be complementary signals by the start-up circuit according to a control signal. Consequently, the relaxation oscillator can be started up successfully. The relaxation oscillator can generate periodic square wave signals. Moreover, during the start-up period of the relaxation oscillator, the generation of the deadlock situation can be avoided.

Abstract: An image sensor includes a first unit. The first unit includes a first photodiode having a first dimension, a second photodiode disposed adjacent the first photodiode and having a second dimension that is greater than the first dimension, a first color filter overlapping the first photodiode and the second photodiode, and a first internal reflector disposed in the first color filter and overlapping the first photodiode. The first internal reflector has an inclined light receiving surface inclined from a top surface of the first color filter toward the second photodiode, and a refraction index of the first internal reflector is smaller than a refraction index of the first color filter.

Abstract: A solid-state image sensor is provided. The solid-state image sensor includes photoelectric conversion elements. The solid-state image sensor also includes a mosaic pattern layer disposed above the photoelectric conversion elements. The mosaic pattern layer includes an infrared-passing segment and color filter segments disposed on the periphery of the infrared-passing segment. The solid-state image sensor further includes a first condensing structure disposed on the mosaic pattern layer. The infrared-passing segment and the color filter segments share the first condensing structure.
