“…4.1. Low noise CIS readout chains may also include correlated multiple sampling (CMS) that can be implemented with analog circuitry [82,49] or performed in the digital domain after the ADC [7]. CMS consists in averaging M samples after the reset and M other samples after the transfer with a sampling period T S , then calculating the difference between the two averages.…”

“…The continuous improvements of CIS, during the first decade of this century, led to the introduction and maturation of pinned photodiodes (PPDs) in CIS. The barrier of one photoelectron noise performance have been crossed using process modification [7] and even in standard CIS technology [8,9]. Process level optimization of CIS can today lead to a dynamic range over a hundred dB [10].…”

“…This is likely due to the fact that the charge carriers in the channel are kept away from the silicon oxide interface [87]. It has been shown that using buried channel NMOS source followers leads to sub-electron noise performance [7]. From a design perspective, thick-oxide transistors, that operate at voltages as high as 3.3 V, are commonly used in CIS pixels.…”

Abstract-The CMOS based sensor design technology has evolved with tremendous applications in MSP domain with enhanced characteristic of maximized S/N ratio. This feature has been obtained with the utilization of pixel-based amplification in addition to minimizing the presence of the noise at the output of the device. It means that the noise present in the various active device of the system has been suppressed with the help of SoC based design technique i.e. three level pixel implementation. This system basically supports all the SoC components such as feedback amplifier, buffers, tapered reset device, etc. The CMOS based smart system has both software as well as hardware modules which in turn behave as a complete system on chip (SoC) and has got tremendous use in mixed signal based applications. The main application fo this system is in the computational analysis of the various images captured from the real world. The author present a novel approach of implementing a smart system based on SoC design approach with required performance in the domain of mixed signal processing. The simulation of the system has been carried out on LabVIEW with optimum results desired. Some the result has been carried with mathematical modeling based approach using MatLAB software. The minimum S/N ratio of the system is 55 dB with 1920 X 1080 frame readout at 550 Hz. Keywords: CMOS sensor, HDTV, FPA, CCD, APS, SoC, LabVIEW, MatLAB, PID algorithm, MSP, CCD.I. INTRODUCTION The advent of the sensor dependent image processing technology has come into existence late back to 1970's with the use of MOS devices. The functioning of this system primarily depends on the utilization of array of image sensors which in turns rely on the proper functioning of the array of CCD technology so as to provide better and enhanced quality imaging arrays. With further advancement in this technology i.e. with the availability of CMOS based smart sensors, the analysis of the image becomes quite simple, cost effective, enhanced accuracy of the results. In this system, CMOS readouts with millions pixel capacity are used in addition to the detector arrays with the help of flip chip fabrication technology i.e. the most important feature of a SoC design based system. The above fig 1 shows the schematic arrangement i.e. crossectional view of the CMOS sensing system.The system on chip design based systems are normally follows the Moore's Law which utilized CMOS technology so as to produce higher performance sensors in various range of visibility. Due to this reason, CMOS technology without any doubt has now emerged the most common approach for the design of both infrared and visible range sensors that in turn finds enormous applications in the domain of MSP. Based on this features, it has been found that most of the mixed signal processing based industrial applications are still dependent on CMOS Image Sensors (CIS) technology as compared to CCD approach [2][3][4][5][6][7][8].
