Abstract :
A low noise amplifier (LNA) for ultra wideband (UWB) and optical communication is presented in this paper. Active impedance matching allows a -3dB bandwidth from dc to 7.8GHz at 50Ω port impedances. At a low power consumption of 1.8 V × 3.6 mA, the amplifier has a power gain of 10.6 dB, a noise figure below 4.4 dB, an input compression of -12 dBm and return losses above 7.8 dB. The fully integrated circuit is fabricated on commercial 0.25μm BiCMOS technology and requires a chip area of 0.45 mm2.
