  • Image sensor and operating method thereof
    Patent number: 11616921
    Abstract: An image sensor includes: a pixel array including a plurality of pixels divided into a plurality of binning areas; a readout circuit configured to, from the plurality of binning areas, receive a plurality of pixel signals including a first sensing signal of first pixels and a second sensing signal of second pixels during a single frame period and output a first pixel value corresponding to the first pixels and a second pixel value corresponding to the second pixels based on the plurality of pixel signals; and an image signal processor configured to generate first image data based on a plurality of first pixel values corresponding to the plurality of binning areas, generate second image data based on a plurality of second pixel values corresponding to the plurality of binning areas, and generate output image data by merging the first image data with the second image data.

  • Integrator, delta-sigma modulator, analog-to-digital converter and applications thereof
    Patent number: 8081098
    Abstract: In one embodiment, the modulator in an analog-to-digital converter includes a first reset switch and second reset switch, each controlled by a reset signal. The first reset switch is connected in a first reset feedback path between an input and an output of an integrator stage, and the second reset switch connected in a second reset feedback path between the input and the output of the integrator stage.
