英文摘要	This paper presents a 14-bit 100-kHz bandwidth incremental sigma-delta analog-to-digital converter suitable for CMOS image sensors with column-parallel ADCs. By using an inverter instead of an operational trans-conductance amplifier (OTA), the total assumption of modulator is dramatically reduced. To further decrease the power consumption, a body bias inverter is proposed in the inverter, enhancing the current efficiency g(m)/I-DS. Since the decimating filter can be realized with a much simpler structure, a full custom circuit design is applied to the schematic design with a self-timing control cell. The proposed single-ended incremental ADC is designed in 0.18 mu m CMOS technology. The simulation result shows that for a 1.8V supply, 30MHz sampling frequency and 150 oversampling ratio, the power consumption is 122.2 mu W, dynamic range is 85dB and the ENOB is 13.26bit.
