A tunable surface-emitting integrated lighting system is constructed using a combination of inorganic light-emitting diodes (LEDs) and transparent organic LEDs (OLEDs). An RB two-color LED is used to supply red and blue light emission, and a green organic LED is used to supply green light emission. Currents of the LED and OLED are tuned to produce a white color, showing different Commission Internationale d’Eclairage (CIE) chromaticity coordinates and correlated color temperatures with a wide adjustable range. Such an integration can compensate for the lack of the LED’s luminance uniformity and the transparent OLED’s luminance intensity.

针对 EMCCD——CCD97的应用，本文在分析其增益曲线特点和倍增时钟功耗的基础上，给出了 CCD97倍增时钟的驱动电路设计。该电路由隔离推挽电路和可调电源组成：隔离推挽电路产生倍增时钟的波形；可调电源可以调节倍增时钟的幅值，且调节精度随着幅值的增加而增加，可以部分抵消 CCD97倍增增益曲线的非线性。文章最后给出了驱动电路的输出波形以及 CCD97的倍增图像。结果表明所设计的驱动电路能够产生符合要求的倍增时钟，可以实现 CCD97的倍增成像和增益调整。
