Abstract: In this research paper, energy efficient GNRFET operational amplifier for Pneumatic applications is designed and simulated at 45nm technology node. DC voltage gain, average power, unity gain bandwidth and output resistance have been computed using HSPICE. Recent work on GNRFET circuit simulations has shown that GNRFETs may have potential in low power applications. It has better DC Gain, low output resistance and extremely less average power as compared ot its CMOS counterpart. Further, the simulation studies have revealed that the performance of the proposed low voltage folded cascode Op Amp can be improved optimized for particle application. The proposed circuit is useful for Aeronautical Engineering, biomedical and other low power applications. In the proposed circuit, the DC Gain is 24.8% higher, Output Resistance is 26.92% lower as compared to Bulk Operational amplifier.
