configuration employing four single output operational transconductance amplifiers (OTAs) …

A novel universal biquad filter topology, realized using Operational Transconductance
Amplifiers as active elements, is presented in this paper. It offers the benefits of orthogonal …

A novel electronically tunable mixed-mode universal biquad by using four single-output and
one dual-output-operational transconductance amplifiers, two grounded capacitors is …

This study presents an electronically tunable low-voltage mixed-mode universal biquad
filter. The proposed filter employs only three current controlled current conveyor trans …

This paper describes a new electronically tunable three inputs and single output voltage-
mode universal biquadratic filter based on simple CMOS operational transconductance …

This paper presents a mixed-mode universal filter using a multiple-input multiple-output
operational transconductance amplifier (MIMO-OTA). The multiple-input OTA is designed …

The transconductance and the transresistance modes might act as the bridge transferring
from voltage-mode to current-mode and vice versa, respectively. A novel mixed-mode …

This paper presents an independently tunable mixed-mode (including voltage, current,
transadmittance, and transimpedance modes, ie four modes) universal biquad filter using …

In this paper, a new low-power multi-mode Gm-C universal filter is proposed in carbon
nanotube field-effect transistor (CNTFET) technology using only 11 inverters and 2 …
