A 3-8GRz wide-band low noise amplifier with novel input matching mechanism is presented in this letter. The proposed circuit uses transistor's intrinsic capacitor Cgd and only one inductor as input matching network to achieve a measured -10 dB input reflection coefficient from 2.75 GM to 12 GM. The fabricated wideband LNA achieves a measured average power gain (S21) of about 10 dB and noise figure of 3.64-5.5dB from 2.75 to 7.5 GHz.
