A new plus-type second-generation voltage conveyor (VCII+) based first-order mixed-mode (MM) all-pass (AP) filter is proposed in this study. The proposed MM AP filter employs two VCII+s, three resistors and one grounded capacitor. It has low input and high output impedances for the current-mode selection while it has low input and low output impedances for the transimpedance-mode selection. The AP filter gain is unity for the current output while it is adjustable for the voltage output via a grounded resistor. However, a single passive component matching condition is needed for the proposed MM AP filter. Complete non-ideal analysis by taking into account all the parasitic resistors and non-ideal gains of the VCII+ is performed. The presented theory is verified through SPICE simulations by using supply voltage of ± 0.9 V and 0.18 μm Taiwan Semiconductor Manufacturing Company complementary metal oxide semiconductor technology parameters.

基于新型混合模式第二代电压传送器的一阶全通滤波器

本研究提出了一种新型的基于正型第二代电压传送器（VCII +）的一阶混合模式（MM）全通（AP）滤波器。拟议的MM AP滤波器采用两个VCII +，三个电阻和一个接地电容器。对于电流模式选择，它具有低输入和高输出阻抗，而对于跨阻抗模式选择，它具有低输入和低输出阻抗。AP滤波器的增益对于电流输出是统一的，而对于通过接地电阻器输出的电压是可调的。但是，提出的MM AP滤波器需要单个无源组件匹配条件。通过考虑所有寄生电阻和VCII +的非理想增益来进行完整的非理想分析。通过使用±0.9 V和0的电源电压进行SPICE仿真，对提出的理论进行了验证。
