In recent time the use of RF mixer has been increased greatly. Gilbert cell is widely used as core of the mixer because it provides high conversion gain, good port-to-port isolation and low even-order distortion. It is found that the linearity of mixer is very good for Multi-Tanh technique by incorporating multiple differential trans-conductance stage but it reaches to very low conversion gain whereas, use of current bleeding technique increase linearity and conversion gain of the mixer by adding current source to increase the bias current at the expense of power consumption. Since, CMOS technology has become dominant because of its several advantages such as low cost, low static power dissipation and low area, the design of low noise amplifier using CMOS technology was top choice for design of Low Noise Amplifier. The single ended and differential LNA was designed to operate in a WCDMA reception range using a BSIM3V2 model (Level 49) CMOS UMC 0.18μm technology in Xcircuit Open source EDA tool. The key issues in the design, gain, noise and linearity were considered. The LNA’s was designed to provide high gain, matching to 50Ω RF system, good linearity.
