中文摘要：
介绍了行间转移CCD芯片KAI-04022的工作原理，根据芯片自身的特点设计了驱动电路。首先，按照信号电平状态多少把驱动信号分为两电平信号和三电平信号两种类型，利用二极管钳位电路和MOSFET驱动器实现两电平信号的输出，而三电平信号的实现是利用AFE芯片AD9920A产生弱驱动能力信号，此信号在压控恒流源电路提供的偏置电流作用下，经过电流型反馈放大器组成的同相射随电路放大输出，为CCD芯片提供驱动。实验结果表明，像素时钟为40MHz时，水平驱动信号的上升沿为4BS，幅度为4．2V，三电平驱动信号的2个上升沿均为50ns，电子快门信号发生电路能够在基底电压的基础上产生幅度为48V、脉宽为4μs的电压脉冲。各驱动电路产生的信号均满足要求，能够为行间转移CCD提供驱动。
英文摘要：
The operating principle of the interline image CCD sensor KAI-04022 was introduced. Due to the characteristics of the chip itself, the driving circuit was designed. The driving signal was divided into two level signals and three level signals according to the number of signal level state. The two level signal output was realized by using the diode clamping circuit and MOSFET driver. The three level signals were realized through the driving signal result from AFE chip AD9920A. Under the offset current supplied by the voltage-controlled constant current source circuit, the weak driving signal was amplified output through the non-inverting emitter follower circuit composed by the current feedback ampli- fier. Ultimately, the driving was supplied for the CCD. The experimental results show that when the pixel clock was 40 MHz, the rising edge of the driving signal was 4 ns and the amplitude was 4.2 V. The two rising edges of the three level driving signal were both 50 ns. And the voltage pulse signal, whose amplitude was 48 V and pulse width was 4 tLs, was produced by the electronic shutter circuit based on the substrate voltage. The signal produced by every driving circuit met the requirements and was ahle to supply the driving for the interline CCD.
