| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this report, we discuss reduction of analog power supply voltage of CMOS image sensors to achieve low power dissipation for applications to mobile, medical, and network cameras. Although power supply voltages of digital circuits are lowered according to advances in fabrication technologies, those of analog circuits remain relatively high, which leads us to spoil the advantage of CMOS image sensors, operation by a single power supply. In addition, dynamic range of analog circuits is degraded by the lowered power supply voltage in exchange of reduced power dissipation. We report that a pulse-width-modulation readout scheme is effective for low voltage operation of CMOS image sensors without degradation of dynamic range. From the experimental results, dynamic range of 57dB for as low as 1.0-V operation of the pixel array block, which suggests the possibility of low-voltage single power-supply operation of CMOS image sensors. | |
