摘要: | A low-power low-noise amplifier (LNA) implemented in 0.18 mu m CMOS technology utilizing a self-forward-body-bias (SFBB) technique is proposed for UWB low-frequency band system. By using the SFBB technique, it reduces supply voltage as well as saves additional bias circuits, which leads to low power consumption of 4.5 mW with low supply voltage of 1.06 V for two drain-to-source voltage drops. The complementary architecture and direct coupling technique between the first two stages also save bias circuits. The measurement result shows that the proposed LNA presents a maximum power gain of 16 dB with a good input impedance matching (S11 < -12 dB) and an average noise figure of 2.65 dB in the frequency range of 3-6.5 GHz. |
