Implementation of Current Reuse Structure in LNAUsing 90nm VLSI Technology for ISM Radio Frequency System

Through this paper it is being unveiled that Two Stage Low Noise Amplifier with cascade inductor common source topology and current reuse configuration designed in 90nm VLSI technology in Cadence-Virtuosois superior to be used in industrial, scientific and medical band when compared to single ended LNA with high gain, high bandwidth and low power. Cascaded Low Noise Amplifier has gain of 127dB, 5.16μW power at 1.2V and Gain Bandwidth Product of 57.03MHz whereas, Single ended Amplifier with a low gain margin of 5.86 dB having 14.9μW power at 1.2V and Gain Bandwidth Product of 30.4MHz.
