摘要：
A wide-band (10 similar to 18GHz) low noise amplifier(LNA) is presented. With transformer feedback in the traditional cascode amplifier, good input matching is achieved from 10 GHz to 18 GHz. The noise figure is below 3.5dB over 10-18GHz. There is no input-matching elements in the input gate of the cascode amplifier, so that the LNA can achieve lower NF. The LNA is designed based on CMOS TSMC 0.18 mu m mixed signal/RF process. With 1.8V supply voltage and three stage amplifiers to achieve wider gain bandwidth, the LNA can achieve input-matching of -12dB over the bandwidth; minimum NIT 2.4dB; gain(S21) of 17dB and 1dB gain compression(P1dB) at -22.6dB. The power consumption is 37.6mW(exclude buffer).
