Abstract: In this research paper, design and simulation of 4T-GNRFET Cascode Amplifier at 45 Nanometer Technology Node has been performed. DC voltage gain, average power, bandwidth and output resistance have been computed using HSPICE Software. Further, the low voltage Cascode Op Amp has better DC Gain, output resistance and less power dissipation. DC voltage gain is 39.5dB, average power is 30 nW, bandwidth is 3.6MHz, Phase Margin 89.30 and Output Resistance 35.15 K-Ohms as obtained from simulation results of HSPICE Software. The proposed circuit of 4T-GNRFET based Cascode Amplifier at 45 Nanometer Technology Node is suitable for A.I. Applications due to astonishing electronic properties of proposed circuit.

Keywords: 4T-GNRFET-Cascode amplifier, Output Resistance, Band width, Average Power, DC Gain
