| 摘 要： | 文章提出了基于状态间法的对数域电流模式一阶低通滤波器和二阶低通滤波器的设计方法。该方法设计的滤波器电路只用晶体管、电流源、接地电容即可实现。同时采用PSPICE对所设计的电路进行了仿真,其仿真结果与理论值相吻合。

| Abstract: | This paper proposes first order low pass log-domain filter and second order low pass log-domain filter of current mode,which are systematically derived by using the state-space synthesis procedure.Only transistors and grounded capacitors are required to realize the filter circuit.PSPICE simulation results are included which are in close conformity with the theoretical results. |
