Abstract: An image sensor includes a pixel array in which pixels having photoelectric conversion elements are arranged in a matrix, color filters corresponding to the pixels and configured to selectively transmit light of at least two different wavelength bands, and microlenses on the color filters. At least some of the microlenses may have different shapes depending on respective wavelength bands that respective corresponding color filters at least partially overlapping with the at least some microlenses are configured to selectively transmit, such that the at least some microlenses are configured to compensate for chromatic aberration between the lights passing through the respective corresponding color filters.

Abstract: A voltage converter includes a converting circuit having an inductor connected to a switching node, a first switch element connected between the switching node and a ground voltage, and a second switch element connected between the switching node and an output node; and a switching control circuit configured to adjust a feedback voltage divided from an output voltage of the output node based on a current state of the inductor, and configured to generate switching control signals for charging the inductor with an input voltage and discharging a voltage charged in the inductor, based on a sensing signal based on a current of the inductor and the adjusted feedback voltage.
