OTRA-based positive/negative grounded capacitance multiplier

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 nonavailable off-the-shelf IC [26][27][28][29][30][31] 4. Requirement of matching constraint 31,33 5. Low MF (<200) [27][28][29][30][31][32] In view of the above, it appears that no single CFOA-based negative capacitance multiplier has been presented yet, which can provide high MF (>1200), employing grounded capacitor without any passive component matching condition(s).…”

“…Requirement of matching constraint 31,33 5. Low MF (<200) [27][28][29][30][31][32] In view of the above, it appears that no single CFOA-based negative capacitance multiplier has been presented yet, which can provide high MF (>1200), employing grounded capacitor without any passive component matching condition(s). Therefore, the main aim of this communication is to present new negative capacitance multiplier circuits with features not available in existing NGCM circuits as shown in Table 1.…”
