A Study Comparing the Performance of Voltage-Mode and Current-Mode KHN Filters

Abstract

The effectiveness of voltage-mode and current-mode Kerwin-Huelsman-Newcomb (KHN) filters, which make use of current feedback amplifiers (CFAs), is thoroughly examined in this work. For a wide range of signal processing needs, these filters may fulfill the usual low-pass, high-pass, and band-pass roles. The current-mode filter is multi-input and single-output (MISO) type, while the voltage-mode filter is single-input and multi-output (SIMO) type. The individual regulation of the natural angular frequency (?o) and quality factor (Q), made possible by CFAs, is an important aspect of the suggested filters. The two circuits are identical in that they both serve the low-pass, high-pass, and band-pass purposes. The suggested filter may regulate the quality factor (Q) and natural angular frequency (?o) separately.
