A 1-inch Optical Format, 80fps, 10.8Mpixel CMOS Image Sensor Operating in a Pixel-to-ADC Pipelined Sequence Mode

1/2-Inch megapixel CMOS digital image sensor

The sensor can be operated in its default mode or programmed by the user for frame size, exposure, gain setting, and other parameters. The default mode outputs an SXGA-size image at 30 frames per second (fps). An on-chip analog-to-digital converter (ADC) provides 10 bits per pixel. FRAME_VALID and LINE_VALID signals are output on dedicated pins, along with a pixel clock that is synchronous with...

A 1/3.4-inch 2.1-Mpixel 240-frames/s CMOS Image Sensor

This paper proposes a 240 frames/s 2.1 M-pixel CMOS image sensor with column-shared cyclic ADC that consumes low power of 90 μW/column at 1.5 V supply and is applicable to the fine pixel pitch of 2.25 μm. The prototype sensor was fabricated in a 0.13-μm 1P4M CMOS technology. The measured DNL and INL are +0.59/-0.83 LSB and +2.8/-3.6 LSB, respectively. The measured maximum pixel rate is 500 Mpix...

R39 A 0.64 microseconds Row-Time CMOS Image Sensor using Gm-Enhanced Repeater Source Follower Buffer and Column Parallel Pipelined ADC

1.5 bit-per-stage 8-bit Pipelined CMOS A/D Converter for Neuromophic Vision Processor

Neuromorphic vision processor is an electronic implementation of vision algorithm processor on semiconductor. To image the world, a low-power CMOS image sensor array is required in the vision processor. The image sensor array is typically formed through photo diodes and analog to digital converter (ADC). To achieve low power acquisition, a low-power mid-resolution ADC is necessary. In this pape...
