Abstract :
A low-power low-noise amplifier (LNA) utilizing resistive inverter configuration feedback amplifier to achieve the broadband input matching purposes, and used of self-forward-body-bias (SFBB) technique to further increase the gain of the whole frequency band and suppress the noise. By using the SFBB technique, it reduces supply voltage as well as saves additional bias circuit. This UWB LNA is implemented by TSMC 0.18μm CMOS technology. The minimum noise figure is 4.8 dB. The amplifier provides maximum gain (S21) of 17.8 dB while drawing 9.67mW from 1.2-V supply. This chip area is 1.274 × 0.771 mm2.
