نویسنده
چکیده
In this paper, a 1 V UWB LNA in TSMC 0.13 um CMOS process technology is designed. The power consumption is only 7.6 mW. By employing RLC peaking, high-frequency poles are moved outside of the 3.1-10.6 GHz band of interest, and a flat power gain and an excellent phase linearity are achieved. By applying DC voltage to the bulk of transistors, a low voltage LNA is accomplished. The proposed LNA is consisted of two stages and uses only 2 inductors. The proposed LNA has the power gain of 8.7 ~ 10.3, low NF of 3.5 ~ 4.2 dB, IIP3 of -6 dB, and good input return loss greater than -17 dB. The -3 dB bandwidth of S21 is from 0.6 to 13 GHz.
