Recently, six new all pass filter (APF) configurations, each employing two current feedback
operational amplifiers (CFOA) and a grounded capacitor, were presented. This …

This article presents a mixed-mode electronically tunable first-order universal filter
configuration employing only one voltage differencing gain amplifier (VDGA), one capacitor …

It is well known that fully differential signal processing is more advantageous than single-
ended signal processing in a noisy environment, and is widely used in audio, video and …

This brief communication presents two current feedback op‐amp (CFOA)‐based simple first‐
order mixed‐mode universal filter topologies—one of them providing first‐order low‐pass …

In this paper, a new mixed-mode first-order universal filter configuration is presented that
employs three operational transconductance amplifiers (OTAs) and one grounded capacitor …

A new first‐order universal filter structure is presented in this article using a single differential
difference current conveyor (DDCC). The proposed circuit can provide three first‐order filter …

This article explores two compact structures to implement dual-mode first-order universal
filters, providing lowpass, highpass, and allpass responses from the same structure. Both …

This paper introduces a novel multifunction filter employing single current operational
amplifier (COA) with MOS-C implementation and a third order sinusoidal oscillator as its …
