Noise suppression in a common-gate UWB LNA with an inductor resonating at the source node
چکیده انگلیسی
In this paper, a noise suppression circuit is proposed and investigated by using resonance technique at the source. Resonance in the source node of the common-gate structure blocks the noise path while transferring the signal from input to output. Through proper analysis, a common gate structure with an active load is improved. As a result, a complementary common gate structure is introduced. A complementary common-gate structure with resonance in the source node can overcome the trade-off between noise and gain in the first stage. Hence, this structure is optimum in terms of the trade-off between gain and noise as well as power dissipation and linearity. Finally, a very-low-noise amplifier is implemented by this method and the post-layout simulation results are obtained: average power gain: 15.8 dB, minimum noise figure: 1.7 dB, bandwidth: 3.1-4.8 GHz, power dissipation of two stage: 11.28 mW, 1-dB compression point at input power: −4.67 dBm, and IP3 at input power: 8.32 dBm.
