压电器件的计算机模拟

Computer simulation of pizo-electric devices

本文从石英晶体、陶瓷陷波器、陶瓷滤波器的物理机理出发,在计算机中,建立了用SPICE程序描述这些器件的模型。代入实际提取的模型参数并与彩色电视接收机电路一起进行的计算机模拟表明,晶振锁相环的起振过程、稳定振荡状态和锁相过程以及陷波及滤波特性与实测情况符合。

Based on the principle of quartz crystals, ceramic traps and ceramic filters, this paper develops the models of these devices by the CAD software of SPICE in computer. With the measured parameters, the computer simulation of color TV receiver circuits shows that the process of oscillation setting up, the steady state of oscillation, the process of phase locking and the characteristics of traps and filters coincide with that measured actually.
