Two new multiple-mode (including voltage, current, transconductance, and transresistance
modes) OTA-C universal biquad filters are proposed. The first proposed circuit uses only …

A fully cascadable (ie, low/high input impedance for current/voltage input signals and
high/low output impedance for current/voltage output signals) mixed-mode (input and output …

A SIMO (single input and multiple outputs) universal mixed-mode (including voltage, current,
transadmittance, and transimpedance modes) biquad with one input (a single voltage or …

None of the previously reported mixed-mode universal filters can achieve the following
important advantage: no need of component matching conditions. This paper presents a …

This paper presents two new high-order OTA-C universal filters. The first proposed filter
structure employs n+ 3 operational transconductance amplifiers (OTAs) and n grounded …

In the paper, a transformation method of frequency filters using Balanced Output
Transconductance Amplifiers (BOTA) into equivalent filtering structures with Universal …

In this paper, three dual-mode (mixed-mode) analog filters using only grounded capacitors
and two to three second-generation current conveyors (CCIIs) are presented. The first …

This article presents a dual‐mode (voltage‐mode and current‐mode) universal biquadratic
filter performing completely standard functions: lowpass, highpass, bandpass, band‐reject …

In this paper, a new high-performance Class AB operational transconductance amplifier
circuit is introduced. Based on flipped voltage follower technique, the proposed OTA showed …

This article presents a current-mode multifunction biquadratic filter performing completely
standard functions low-pass, high-pass, band-pass, band-reject and all-pass functions. The …
