Mixed-mode biquad filter employing single active element

2013 IEEE 4th Latin American Symposium on Circuits and Systems (LASCAS), 2013
Mixed-mode filters are useful circuit blocks in modern microelectronic systems applications, such as controls and voice and data communications. In this paper, a mixed-mode biquad filter is proposed providing voltage, current, transconductance and transresistance operating modes.

Fully Digitally Programmable Generalized Mixed Mode Universal Filter Configuration

Circuits, Systems, and Signal Processing, 2016
This paper presents five feature-enriched hardware-efficient mixed mode universal filter (UF) biquads using digitally programmable (DP) current conveyors (CC). Common features of proposed UFs include use of only two grounded capacitors, operation in all the four modes, realization of all the filter functions, independently programmable filter ...

A novel mixed-mode current-conveyor-based filter

International Journal of Electronics, 2004
A new mixed-mode biquad circuit is presented. The circuit uses six single-output plus-type second-generation current-conveyors (CCII+s), a single dual-output CCII+, two grounded capacitors, eight resistors, at least two of them permanently grounded, and can realize lowpass, highpass, bandpass, notch, lowpass notch, highpass notch and allpass responses ...

A novel mixed-mode OTA-C universal filter

International Journal of Electronics, 2005
A novel mixed-mode biquad circuit is presented. The circuit uses six single-output- and one dual-output-operational transconductance amplifiers, two grounded capacitors; and can realize lowpass, highpass, bandpass, notch, lowpass-notch, highpass-notch and allpass responses from the same topology.

High-order mixed-mode OTA-C universal filter

AEU - International Journal of Electronics and Communications, 2009
Abstract The transconductance and the transresistance modes might act as the bridge transferring from voltage mode to current mode and vice versa, respectively. This brief presents a universal mixed-mode high-order OTA-C filter structure using n + 1 single-output OTAs, one multi-output OTA, and n grounded capacitors.

High-order DDCC-based general mixed-mode universal filter

IEE Proceedings - Circuits, Devices and Systems, 2006
The transconductance and the transresistance modes might act as the bridge transferring from voltage mode to current mode and vice versa, respectively. This paper presents a new mixed-mode (including voltage, current, transconductance, and transresistance modes) high-order universal filter structure using n+1 differential difference current conveyors ...

Novel Electronically Tunable Mixed-Mode Biquad Filter

2011
This paper presents a novel electronically tunable mixed-mode biquad filter. The proposed filter employs only three multi-output current controlled current conveyor trans-conductance amplifiers (MO-CCCCTAs) and two grounded capacitors. With the current as an input, the proposed filter can realize low pass (LP), band pass (BP), high pass (HP), band ...

Digitally programmable current-conveyor based mixed-mode universal filter

International Journal of Electronics Letters, 2014
This paper presents a novel mixed-mode universal filter (UF) using digitally programmable second-generation current conveyor. The proposed single filter configuration is capable of realising all the standard filter functions in both inverting and non-inverting forms in all the four modes, namely voltage mode, current mode, trans-impedance mode and ...
