Contributor Theuwissen, A.J.P. (mentor) Faculty Electrical Engineering, Mathematics and Computer Science Department Microelectronics & Computer Engineering Programme Microelectronics Date 2015-09-14 Abstract This thesis presents a 1-Mega pixels high-dynamic range and UV sensitive image sensor in 0.18 µm technology with 14-bit interleaved 64Ms/s SAR ADC. It can achieve 64 fps and 101 dB dynamic range. The pixel array contains three kinds of pixel: UV pixel, visible pixel and low blue pixel. Those three kinds of pixel form a special 4×4 kernel to meet the technology etching requirement and an optimized modulation transfer function (MTF). The extended floating diffusion method is introduced to achieve the high-dynamic range. An odd/even time interleaved analog readout method is used to increase the read out speed. To read out column outputs, the row driver block, column loads, S/H circuits, readout buffers and digital control block are all implemented in this design. A 14-bit interleaved 64Ms/s SAR ADC is used to digitize the analog signals. The ADC block contains 16 14-bit 4Ms/s SAR ADCs. To achieve a 4Ms/s 2V peak-to-peak 14-bit ADC, a high speed comparator with offset calibration is implemented. Two 14-bit serializers are used to serialize the ADC output in this design.
