Analysis of Active Pixel Sensor Readout Circuit
Active pixel sensor (APS) CMOS image sensor high-speed imaging readout electronics
2015/8/12
This brief provides a detailed analysis of active pixel sensor, pixel and column circuit. Surprisingly, we find that shorter readout times can be achieved by reducing the bias current and hence reduci...
A 640 512 CMOS Image Sensor with Ultrawide Dynamic Range Floating-Point Pixel-Level ADC
Analog-to-digital conversion (ADC) CMOS image sensors digital cameras dynamic range image sensors mixed analog–digital integrated circuits pixel-level ADC video cameras
2015/8/12
Analysis results demonstrate that multiple sampling can achieve consistently higher signal-to-noise ratio at equal or higher dynamic range than using other image sensor dynamic range enhancement schem...
A Nyquist-Rate Pixel-Level ADC for CMOS Image Sensors
Analog-to-digital conversion cameras CMOS image sensors image sensors mixed analog–digital integrated circuits pixel-level analog-to-digital converter (ADC) video cameras
2015/8/12
A multichannel bit-serial (MCBS) analog-to-digital converter (ADC) is presented. The ADC is ideally suited to pixel-level implementation in a CMOS image sensor. The ADC uses successive comparisons to ...
Concerning Spin as Mind-pixel:How Mind Interacts with the Brain through Electric Spin Effects
spin mind-pixel electric spin effect spin transverse force
2015/7/28
Electric spin effects are effects of electric fields on the dynamics/motions of nuclear/electron spins and related phenomena. Since classical brain activities are largely electric, we explore here a m...
Hydrogenated amorphous silicon thin-film transistor (a-Si:H TFT) pixel electrode circuit with a function of current scaling is proposed for active-matrix organic light-emitting displays (AM-OLEDs). In...
We fabricated and characterized the hydrogenate amorphous-silicon thin-film transistor (a-Si:H TFT) pixelelectrode circuit with the current-scaling function that can be used for active-matrix organic ...
