Abstract :
A fully integrated 2 V 2.4 GHz ISM (Industrial Scientific and Medical) frequency band LNA (Low Noise amplifier) is proposed. The LNA is designed with 0.3 μm process. The noise figure including the resistance of inductors has been considered. An inductor is added between the MOS of cascode circuits to improve the matching and increase power gain. With a 2 V supply, the LNA achieves a power gain (S21) of 19.9 dB, noise figure of 2.5 dB, and power dissipation 14.7 mW. Also, the input third-order intercept point (IIP3) is 2 dBm, and an input 1-dB compression point (P1 dB) is -12 dBm. The reverse isolation is -47.8 dB
