天文级电荷耦合器件的高压CMOS控制接口
High Voltage CMOS Control Interface for Astronomy - Grade Charged Coupled Devices
摘要：
Pan-STARRS望远镜由一组较小的反射镜组成，由千兆像素的CCD阵列观察。这些焦平面采用正交传输CCD（OTCCD）来实现片上图像稳定。每个OTCCD都具有外部控制的高级逻辑功能。研制了一种CMOS高压接口器件，用于从读出和控制系统STARGRASP提供合适的电压信号电平。OTCCD芯片的输出电平范围为-3.3V至16.7V，根据负载电容（50 pF和1000 pF）的不同，需要两种不同的输出驱动强度，驱动电流为24 mA，上升时间为100 ns。该芯片中还包含其他测试ADC结构，以评估下一版本芯片的未来功能添加。
英文摘要：
The Pan-STARRS telescope consists of an array of smaller mirrors viewed by a Gigapixel arrays of CCDs. These focal planes employ Orthogonal Transfer CCDs (OTCCDs) to allow on-chip image stabilization. Each OTCCD has advanced logic features that are controlled externally. A CMOS Interface Device for High Voltage has been developed to provide the appropiate voltage signal levels from a readout and control system designated STARGRASP. OTCCD chip output levels range from -3.3V to 16.7V, with two different output drive strenghts required depending on load capacitance (50pF and 1000pF), with 24mA of drive and a rise time on the order of 100ns. Additional testing ADC structures have been included in this chip to evaluate future functional additions for a next version of the chip.
