A New Voltage Mode KHN Biquad Using VCII

Abstract

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 ([Formula: see text]). 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.
