In this paper, we present six area-efficient transimpedance type second-order analog filters. There are many applications where the available signal is current, however the necessary signal for further processing is voltage type. For such applications the presented circuits will be a useful solution. The technique employed is called MOS-only technique and to the best of our knowledge this is the first attempt to implement transimpedance type filters with MOS-only technique. Starting from the core circuit biasing is illustrated and the functionality is shown with LT SPICE simulations using TSMC 0.18u technology parameters. From six core circuits one circuit is selected and the design is completed for illustration purpose.

在本文中，我们提出了六个面积有效的跨阻型二阶模拟滤波器。在许多应用中，可用信号是电流，但是进一步处理所需的信号是电压类型。对于此类应用，提出的电路将是一个有用的解决方案。所采用的技术称为纯MOS技术，据我们所知，这是首次尝试使用纯MOS技术实现跨阻型滤波器。从核心电路偏置开始，并说明了使用TSMC 0.18u技术参数进行LT SPICE仿真的功能。从六个核心电路中选择一个电路，并出于说明目的完成了设计。
