Abstract
A 3-8 GHz 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 GHz to 12 GHz. The fabricated wideband LNA achieves a measured average power gain (S21) of about 10 dB and noise figure of 3.64-5.5 dB from 2.75 to 7.5 GHz.
