HSPICE software was used to develop and simulate CNTFETs. The op-amps were designed using 0.9[Formula: see text]V input supply voltage. The proposed structures were formed either using CNTFETs only known as pure CNTFET-IFFC-2SOA or hybrid structures consisting a mix of both CNTFETs and conventional CMOS named as PCNTFET-NMOS-IFFC-2SOA and NCNTFET-PMOS-2SOA. The comparative investigation revealed that CNT-based structures performed significantly better than the traditional CMOS-based devices. In the instance of CNTFET-IFFC-2SOA, there was a considerable improvement in DC gain, power dissipation, phase margin, and CMRR. The DC Gain increased by 140.92%, the CMRR increased by 32.94%, and the phase margin increased by 4.9%. Furthermore, at the 32[Formula: see text]nm technology node, a GNRFET-based structure was designed and compared to conventional CMOS and pure CNTFET-based IFFC-2SOA. It was discovered that the DC gain, phase margin, and power dissipation obtained by the CNTFET-based structure were superior to both. The DC Gain of CNTFET-IFFC-2SOA was 156.79% more than that of GNRFET-IFFC-2SOA. To confirm the workability of the proposed circuits, an integrator was designed and simulated as its application. The CNTFET-based IFFC-2SOA integrators showed better integration action than the traditional CMOS-IFFC-2SOA. <\/jats:p>","DOI":"10.1142\/s0218126624501573","type":"journal-article","created":{"date-parts":[[2023,11,28]],"date-time":"2023-11-28T13:55:55Z","timestamp":1701179755000},"source":"Crossref","is-referenced-by-count":3,"title":["Design, Simulation and Comparative Analysis of Two Stage Operational Amplifier Based on CNTFETs Using Indirect Feedback Frequency Compensation"],"prefix":"10.1142","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1010-3535","authenticated-orcid":false,"given":"Mir Bintul","family":"Islam","sequence":"first","affiliation":[{"name":"Electronics and Communication Engineering Department, Jamia Millia Islamia, New Delhi 110025, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Nizamuddin","sequence":"additional","affiliation":[{"name":"Electronics and Communication Engineering Department, Jamia Millia Islamia, New Delhi 110025, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.
