“…There are many CFOA-based analogue circuits available in open literature; see, e.g. [1][2][3][4][5][6][7][8][9][10][11][12]. In [1], many analogue circuits using CFOA as active element are described, including inductor and impedance simulators, active filters, oscillators and non-linear circuits.…”

“…In [1], many analogue circuits using CFOA as active element are described, including inductor and impedance simulators, active filters, oscillators and non-linear circuits. Most recently, several analogue circuits using CFOAs have been proposed [2][3][4][5][6][7][8][9][10][11][12]. Therefore, CFOA is an attractive device that should be developed.…”

New negative‐grounded capacitance multiplier circuits

“…Since, in this paper, we have proposed new configurations of negative capacitance multiplier; therefore, a brief summary of previously reported negative capacitance multipliers employing different ABBs along with CFOAs [25][26][27][28][29][30][31][32][33][34][35][36][37] has been presented here to put the proposed work in proper perspective.…”

“…Use of more than one ABB 25,26,[28][29][30][31][32][34][35][36][37] 2. Employment of floating capacitor 25,[27][28][29]31,32,[34][35][36][37] 3. Use of nonavailable off-the-shelf IC [26][27][28][29][30][31] 4.…”
