本文介绍了一种400H×256V像素20 Mfps全局快门CMOS型图像传感器，每个像素有128个片上存储器，具有更高的灵敏度和功耗性能。由于基于1P6M0.18μm cmos图像传感器工艺的工艺技术的发展和电源电压降低3.3V的信号读出电路的优化，芯片的填充因子、转换增益和读出增益都比原来的芯片有所提高，同时光灵敏度提高了8倍，功耗降低了50%。根据捕获的UHS现象的电影视频，确认性能改进的影响是显著的。
In this paper, a 400H × 256V pixels 20 Mfps global shutter CMOS image sensor having 128 on-chip memories per pixel with improved sensitivity and power consumption performances is demonstrated. Due to the process technology development based on a 1P6M 0.18 μm CMOS image sensor process and the optimization of the signal readout circuitry with decreased supply voltage of 3.3 V, the fill factor, the conversion gain and the readout gain were all improved from the previous chip and an eight times higher light sensitivity and a 50 % decrease of power consumption were achieved simultaneously. The impact of the performance improvements was confirmed to be significant based on the captured movie video of UHS phenomena.
