Abstract :
A low power ultra-wideband (UWB) common-gate low noise amplifier (CGLNA) for IEEE 802.15.3a is presented. In order to save the power consumption, a current-reuse technology is used. For extending the bandwidth, the proposed circuit uses and the stagger tuning technique of two stacked stages with different resonant frequencies. The circuit is simulated with TSMC 0.18 mum mixed signal/RF CMOS process technology. The post-layout circuit simulation results show the proposed UWB CGLNA can achieve a maximum power gain (S21) of 13.5dB with the -3dB bandwidth from 3.1GHz to 10GHz. The input reflection coefficient S11 and output reflection coefficient S22 are both less than -10dB, a minimum noise figure of 3.55dB, and an input third-order intercept point IIP3 of -6.4dBm. The power dissipation is 2.7mW at 1.5V supply voltage.
