“…Though CFOAs were initially proposed to work in conditions similar to OAs with two input terminals and a single output, 12,13 the availability of the compensation node adds flexibility to the topology, allowing alternative and novel applications. [14][15][16][17] Our application is one such. Unfortunately, the number of commercial CFOA devices that have the compensation node externally available is scarce, the model AD844 being a remarkable exception.…”

“…A differential voltage buffer (DVB), electronically controllable CCII (ECCII‐) and a single‐capacitor based capacitance multiplier has been presented in Jerabek et al 29 The reported circuit can also be used as lossy capacitance multiplier while considering the output resistance of DVB and input resistance at input terminal of ECCII‐. In Özer et al, 30 a generic grounded capacitance multiplier (GCM) has been presented, with four lossy capacitance multipliers implemented using two CFOA and appropriate passive components. An electronically tunable series RC simulator circuit has been presented in Moonmuang et al 31 using two VDBA and one grounded capacitor with an operating frequency range of 10 kHz–100 MHz.…”

“…From Table 1, it is seen that there have been limited number of designs of lossy capacitance multipliers in the open literature using various ABBs such as VDTA, VDBA, CFOA, OTA, DVTC, and ECCII. [22][23][24][25][26][27][28][29][30][31][32][33][34] A circuit with parallel immittance simulator having negative resistance and positive capacitance is useful in oscillator design and only one circuit, using two CFOAs, two resistors and one capacitor, has been reported in Özer et al 30 Therefore, in this paper, a new lossy capacitance multiplier circuit is proposed using a single CFDITA, one resistor and one capacitor. The performance of the proposed circuit is validated using 0.18 μm CMOS technology with CFDITA, and experimental results using commercially available ICs AD844 and LM13700 are included to support its performance.…”

“…For low frequency applications, mostly higher value capacitance is used that increases the size of capacitor (which requires large area on silicon chip and not suitable from the view point of IC fabrication) 1–3 . Consequently, to alleviate these limitations, researchers and circuit designers have stimulated various positive CMs 4–24 and negative CMs, 25–37 employing different active building blocks. These CMs may find various applications in the design of low frequency filters, low frequency oscillators, and integration of a phase‐locked loop filter 38 .…”
