Abstract :
This paper presents a temperature variation tolerant 60 GHz Low Noise Amplifier (LNA) for mm-wave communication systems. The proposed temperature compensated bias circuit is utilized for the common source LNA. The temperature variation of S21 is 1.71dB in the temperature range from -20°C to 100°C, which is 47% lower than the value reported in previous work. The Figure of Merit (FoM) of the proposed LNA at 25°C is comparable to the top value of state-of-the-art work and FoM at 100°C is also comparable to those reported in the literature operated at room temperature.
