Download A Biologically Inspired CMOS Image Sensor Book in PDF, ePub and Kindle
Biological systems are a source of inspiration in the development of small autonomous sensor nodes. The two major types of optical vision systems found in nature are the single aperture human eye and the compound eye of insects. The latter are among the most compact and smallest vision sensors. The eye is a compound of individual lenses with their own photoreceptor arrays. The visual system of insects allows them to fly with a limited intelligence and brain processing power. A CMOS image sensor replicating the perception of vision in insects is discussed and designed in this book for industrial (machine vision) and medical applications. The CMOS metal layer is used to create an embedded micro-polarizer able to sense polarization information. This polarization information is shown to be useful in applications like real time material classification and autonomous agent navigation. Further the sensor is equipped with in pixel analog and digital memories which allow variation of the dynamic range and in-pixel binarization in real time. The binary output of the pixel tries to replicate the flickering effect of the insect’s eye to detect smallest possible motion based on the change in state. An inbuilt counter counts the changes in states for each row to estimate the direction of the motion. The chip consists of an array of 128x128 pixels, it occupies an area of 5 x 4 mm2 and it has been designed and fabricated in an 180nm CMOS CIS process from UMC.

Download Low-Power CMOS Digital Pixel Imagers for High-Speed Uncooled PbSe IR Applications Book in PDF, ePub and Kindle
This book describes the development of a new low-cost medium wavelength IR (MWIR) monolithic imager technology for high-speed uncooled industrial applications. It takes the baton on the latest technological advances in the field of vapor phase deposition (VPD) PbSe-based MWIR detection accomplished by the industrial partner NIT S.L., adding fundamental knowledge on the investigation of novel VLSI analog and mixed-signal design techniques at circuit and system levels for the development of the readout integrated device attached to the detector. In order to fulfill the operational requirements of VPD PbSe, this work proposes null inter-pixel crosstalk vision sensor architectures based on a digital-only focal plane array (FPA) of configurable pixel sensors. Each digital pixel sensor (DPS) cell is equipped with fast communication modules, self-biasing, offset cancellation, analog-to-digital converter (ADC) and fixed pattern noise (FPN) correction. In-pixel power consumption is minimized by the use of comprehensive MOSFET subthreshold operation.

Two physical implementations featuring sub-0.5-electron RMS are subsequently presented to verify the proposed noise reduction techniques and provide a full characterization of a VGA imager. Based on the verified noise calculation, the impact of the technology downscaling on the input-referred noise is also studied. Further, the thesis covers THz CMOS image sensors and presents an original design that achieves ultra-low-noise performance. Last but not least, it provides a comprehensive review of CMOS image sensors.

Download Analog Readout Methods for CMOS (complementary Metal-oxide-semiconductor) Image Sensors Utilizing a Global Feedback Book in PDF, ePub and Kindle
"Ever since the invention of Charged Coupled Devices (CCD) and CMOS image sensors, there have been tremendous development efforts towards the creation of digital cameras, which rapidly replaced traditional analog and film cameras. Despite their leading role in the market today, most digital cameras still exhibit worse image quality than film cameras. Many efforts have been made to improve the performance of digital images, such as increased dynamic range and reduced readout noise. As one of the fastest growing industries worldwide, CMOS imaging ranges from high quality digital still cameras to low quality consumer end products. Compared to CCD image sensors, CMOS image sensors allow low power, low cost and on-chip signal processing, which allow them to become more and more prominent. However, the demand for low noise, high readout speed and high dynamic range is still a big concern for CMOS imagers. The goal of this work is to improve the readout time while decreasing the readout noise by employing a modification to the standard Active Pixel Sensor (APS) design to retain high fill factor. The first part of this work focused on a new design named Current Sensing Active Pixel (CSAP) sensor. The design was an analog CMOS image sensor readout architecture implemented in a standard 0.35 [microns] CMOS process, operating from a 3.3 V power supply with faster readout settling times than the standard APS design. The standard APS source follower configuration is used in the pixel part of the CSAP design to obtain a high fill factor. The CSAP design also employed an out-of-pixel readout amplifier in the negative feedback topology with respect to the pixel unit to increase the pixel's current driving capabilities and thereby reduce the settling time at the output. As a result of improved settling time, the 1/f noise contributed by the inpixel source follower transistor may be significantly reduced by the correlated double sampling (CDS) operation commonly used in analog image sensor readout methods. The fabricated CSAP chip prototype was successfully tested and some of the performance improvements were also demonstrated. The other part of this thesis was a new design named Reconfigurable Active Pixel Sensor (RAPS). It was also an analog CMOS image sensor readout architecture implemented in a standard 0.35 [microns] CMOS process operating from a 3.3 V power supply. This design eliminated the need for the external correlated double sampling (CDS) circuit that is used in traditional APS designs. It employed a reconfigurable differential-input readout amplifier that may be used in both the reset and the readout phases of the image sensor operation. As a result, the DC offset was removed, the flicker noise was differentiated, and the reset noise was greatly reduced by employing the amplifier in an active reset configuration. Gain related fixed pattern noise (FPN) was also reduced by the higher open-loop gain of the differential amplifier. This design retained a high fill factor since the pixel unit utilized the same number and size of transistors as the standard APS design"--Leaves iv-v.

Download Focal-Plane Sensor-Processor Chips Book in PDF, ePub and Kindle
Focal-plane sensor-processor imager devices are sensor arrays and processor arrays embedded in each other on the same silicon chip. This close coupling enables ultra-fast processing even on tiny, low power devices, because the slow and energetically expensive transfer of the large amount of sensory data is eliminated. This technology also makes it possible to produce locally adaptive sensor arrays, which can (similarly to the human retina) adapt to the large dynamics of the illumination in a single scene This book focuses on the implementation and application of state-of-the-art vision chips. It provides an overview of focal plane chip technology, smart imagers and cellular wave computers, along with numerous examples of current vision chips, 3D sensor-processor arrays and their applications. Coverage includes not only the technology behind the devices, but also their near- and mid-term research trends.
