The objective of this paper was to propose a second generation voltage conveyor (VCII)-based new voltage mode biquad, equivalent to Kerwin–Huelsman–Newcomb (KHN) biquadratic circuit. The proposed circuit helped to efficiently add and subtract voltages by exploiting the virtual ground at one of the terminals of VCII, and without compromising on the features of the filters, such as the independent tuning of the quality factor (Q) and characteristic frequency (ωo). The proposed circuit’s viability has been verified through LTspice simulations. The paper also presented the nonideal, the sensitivity, distortion, linearity and Monte Carlo analysis of the filters of the proposed circuit.

一种使用VCII的新型电压模式KHN Biquad

本文的目的是提出一种基于第二代电压传送器 (VCII) 的新电压模式双二阶，等效于 Kerwin-Huelsman-Newcomb (KHN) 双二次电路。所提出的电路有助于通过利用 VCII 端子之一的虚拟接地来有效地增加和减少电压，并且不会影响滤波器的特性，例如品质因数的独立调谐（问) 和特征频率 (ω○）。所提出的电路的可行性已通过 LTspice 仿真得到验证。本文还介绍了所提出电路的滤波器的非理想、灵敏度、失真、线性和蒙特卡罗分析。
