介绍了一种电荷载流子倍增寄存器(CCM)电极间隙的传输线模型,通过求解其波动方程得到了电荷载流子倍增寄存器电极间隙的电势分布及电场分布。模拟分析表明:电荷载流子倍增寄存器电极间隙的电势分布是与电荷载流子倍增寄存器工作频率相关的函数。电势分布沿信号电荷密度流方向衰减且电荷载流子倍增寄存器工作频率越高,电势衰减越快。电荷载流子倍增寄存器工作频率趋于零时,电场强度分布均匀。随着工作频率增加,电场分布呈现非均匀分布。频率越高,电场强度的峰值越大,沿信号电荷密度流方向衰减越明显。因此,电荷载流子倍增寄存器工作频率越高,其电荷倍增因子越小。
A transmission line model of the charge carrier multiplication register (CCM) electrode gap is introduced. By solving its wave equation, the potential distribution and the electric field distribution of the charge carrier multiplication register electrode gap are obtained. Simulation analysis shows that the potential distribution of the charge carrier multiplication register electrode gap is a function of the operating frequency of the charge carrier multiplication register. The potential distribution decays in the direction of signal charge density flow and the higher the operating frequency of the charge carrier multiplication register, the faster the potential decay. Charge carrier multiplication register operating frequency tends to zero, the electric field intensity distribution. As the operating frequency increases, the electric field distribution presents a non-uniform distribution. The higher the frequency, the greater the peak of the electric field intensity, the more obvious the attenuation along the signal charge density flow direction. Therefore, the higher the charge carrier multiplication register operating frequency, the smaller the charge multiplication factor.
