摘要：

A capacitive shunt feedback LNA input matching network is demonstrated which offers matching, good noise performance, low component count and low area consumption. A prototype 9 GHz LNA vehicle amplifier is designed and fabricated in a 130nm RF-CMOS process. The measured amplifier has 20.5dB of gain at 8.8GHz with input and output match of -15dB and -8dB respectively. It has 1.4 GHz of 3dB-bandwidth around 9 GHz with the noise figure of 1.7dB at the center frequency and below 2dB across the band. Large signal measurements reveal that the amplifier can deliver -2dBm of power to the 50 Omega output load at its 1dB compression point. It draws 23mA of current from a 1.2V supply. The chip occupies an area of 0.64mm(2).
