Abstract : A two stage cascode Low Noise Amplifier (LNA) is designed in 130 nm SiGe HBT. The work focuses on achieving a low Noise Figure (NF), high linearity, and high gain for the LNA in the frequency band of 57.24 GHz-65.88 GHz to be operated in all the four channels of IEEE 802.11ad standard. A modified Derivative SuperPosition technique is used in the first stage of the cascaded LNA to improve the linearity of the circuit. Post layout Electromagnetic (EM) simulation results of the proposed LNA achieves a peak gain of 20.19 dB at 59.5 GHz, linearity (IIP3)) of 2 dBm at the maximum gain and also achieved a NF of 4.1 dB - 4.8 dB in the operating band of frequency. DC power consumption of the proposed circuit is 9.2 mW from a supply voltage of 1.2 V.
