Abstract: This paper presents design of Transformer Feed-Back (TFB) Common Source (CS) Low Noise Amplifier (LNA)and implemented in 65 nm CMOS process parameters for operation at 60 GHz. The LNA is composed of four cascaded CS stages by utilizing gate-source TFB at the input side for input impedance matching to reduce the noise figure. The drain-source TFB is applied to the remaining stages for gain improvement, interstage and output matching. The designed LNA is simulated with Advanced Design System (ADS) and verified its functionality with respect to Noise Figure (NF), Gain, Linearity, Power dissipation and Stability. Simulated results of the proposed LNA show 23.91 dB of gain, 5.58 dB of NF and -7 dBm of IIP3 to accomplish linearity. The Figure of Merit (FoM) describes as a component of the linearity, gain and NF is 27 while drawing 15 mA from a 1.0 V supply.
