A New Versatile Universal Biquad Configuration for Emerging Signal Processing Applications

Abstract

The paper introduces a new versatile universal biquadratic configuration based on two fully differential second generation current conveyors without need of input matching conditions. The proposed circuit consists of two fully differential second generation current conveyors, four resistors and two grounded capacitors. The proposed biquad configuration provides all five standard filtering responses: low-pass, high-pass, band-pass, band-reject and all-pass in voltage-mode, transadmittance-mode, current-mode and transimpedance-mode. The proposed circuit is single-input multiple-outputs type, so all responses are available simultaneously. Moreover, extra inverting amplifier and double-type amplifier are also not required in the proposed circuit for any filtering response. The nonideal and parasitic effects of fully differential second generation current conveyor on the proposed circuit have also been investigated. HSPICE simulation results have been incorporated to validate the proposal.

Voltage Differencing Current Conveyor Based Voltage-Mode and Current-Mode Universal Biquad Filters with Electronic Tuning Facility

“…The performance parameters of the designed filters are summarized and compared with other previously published related works [1,[3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] in Table 4. It depicts that the designed filters consume least power among all the other circuits.…”

Novel Electronically Tunable Biquadratic Mixed- Mode Universal Filter Capable of Operating in MISO and SIMO Configurations

“…The non-ideal analysis considering the effect of nonideal current, voltage, and transconductance transfer gains is carried out for SIMO (VM and CM) and MISO (VM and CM) configurations to see its effect on the transfer function, f 0 , and Q of the proposed filters. The modified expressions of filter transfer functions, f 0 , and Q for the SIMO, and MISO configurations are presented in Equations (32)(33)(34)(35)(36)(37)(38)(39)(40)(41)(42)(43)(44). The sensitivities are low and have absolute values not higher than unity.…”

“…Current conveyor and its variants are the basic building blocks which are commonly used for circuit design using current‐mode approach (Channumsin et al, ; Chaturvedi & Maheshwari, ; Chaturvedi et al, ; Chaturvedi et al, ; El‐Adawy et al, ; Herencsar et al, ; Kumar & Chaturvedi, ; Kumar & Chaturvedi, ; Kumar & Chaturvedi, ; Kumar, Chaturvedi, & Maheshwari, ; Kumar, Chaturvedi, Mohan, & Maheshwari, ; Lee & Chang, ; Maheshwari, ; Maheshwari & Khan, ; Maheshwari et al, ; Minaei & Yuce, ; Minaei et al, ; Mohan et al, ; Mohan et al, ; Pushkar et al, ; Sangyaem et al, ; Supavarasuwat et al, ; Tangsrirat et al, ; Yuce, ; Yuce & Tez, ; Yucel & Yuce, ). Therefore, the multifunction filters based on current‐mode approach (Channumsin et al, ; Chaturvedi et al, ; Chaturvedi & Maheshwari, ; Herencsar et al, ; Kumar & Chaturvedi, ; Maheshwari, ; Maheshwari et al, ; Maheshwari & Khan, ; Minaei et al, ; Minaei & Yuce, ; Mohan et al, ; Pushkar et al, ; Sangyaem et al, ; Supavarasuwat et al, ; Tangsrirat et al, ; Yuce, ; Yuce & Tez, ; Yucel & Yuce, ) are found more advantageous over multifunction filters based on voltage‐mode approach (Minaei et al, ; Tsukutani et al, ; Tsukutani et al, ).

“…On the other hand, the current-mode approach has been widely used in the last decade to design different types of analog circuits due to its several advantages over voltage-mode approach. Current conveyor and its variants are the basic building blocks which are commonly used for circuit design using current-mode approach (Channumsin et al, 2012;Chaturvedi & Maheshwari, 2011;Chaturvedi et al, 2018;Chaturvedi et al, 2019;El-Adawy et al, 2000;Herencsar et al, 2013;Kumar & Chaturvedi, 2017a;Kumar & Chaturvedi, 2017b;Kumar, Chaturvedi, Mohan, & Maheshwari, 2017;Lee & Chang, 2009;Maheshwari, 2008;Maheshwari & Khan, 2005;Maheshwari et al, 2010;Minaei & Yuce, 2009;Minaei et al, 2003;Mohan et al, 2014;Mohan et al, 2016;Pushkar et al, 2014;Sangyaem et al, 2017;Supavarasuwat et al, 2018;Tangsrirat et al, 2013;Yuce, 2017;Yuce & Tez, 2018;Yucel & Yuce, 2017).
