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

This paper introduces an electronically tunable mixed-mode universal biquad filter
configuration employing four single output operational transconductance amplifiers (OTAs) …

In this paper a mixed‐mode (input and output signals can be current or voltage) Kerwin–
Huelsman–Newcomb (KHN) biquad with low/high input impedance and high/low output …

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 …

Featured Application Active analog filters are widely used for frequency duplexing in radar
and radio communication systems, impedance matching in power amplifiers, anti-aliasing in …

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 a new mixed-mode universal filter based on a differential difference
transconductance amplifier (DDTA). Unlike the conventional transconductance amplifier …

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