Abstract

LNA is an electronic amplifier that is required in receiver systems to increase the amplitude of the very low level signals from the antenna without adding too much noise. Software Advance Design System (ADS) was used to simulate the circuit and design the layout. LNA was designed using cascode topology with feedback techniques which produces better matching and unconditionally stable over the entire desired frequencies. For the 2.4 GHz operation, the amplifier achieves gain of 14.949 dB, noise figure of 1.951 dB and input reflection coefficient of -10.419 dB. With operating voltage supply at 3V, the total current consumption is 13 mA. For 3.5GHz amplifier, gain is 22.985 dB, noise figure is 1.964dB, input reflection coefficient is -12.427 dB and current consumption is 18 mA.
