Design of Highspeed CMOS Image Sensor for Hyperspectral Imaging
For the imaging requirements such as high frame rate, global shutter and adjustable output channel amount, a kind of CMOS image sensor for hyperspectral imaging is proposed. The schematic plan and working principles of 8T pixel structure and readout circuit are introduced in detail. Postsimulation and tapeout of this sensor were completed, and the experimental results show the design meets the expectation by achieving targeting features and realizing highspeed and lownoise analog signal output under the condition of large layout area and small amount of output channels. The pixel array size of 2048×256 and the pixel pitch of 24μm×24μm are achieved, the maximum signal output frequency for a single channel is 40×106pixel/s and the frame rate can reach up to 4000f/s, being able to meet the general requirement of a hyperspectral imaging system.
