Abstract :

ABSTRACT: This paper presents the low noise amplifier for ultra wide-band applications.the UWB LNA is design in 0.18µm CMOS technique to achieve low noise figure ,low power consumption and high gain. To attain the low power dissipation and low supply voltage,foldedcascode with current reused technique is utilized in first stage. Negative feedback is adopted to extend the bandwidth. using the proposed technique ,a maximum gain of 12.7 dB and minimum noise figure of 2dB is achieved. The total power consumption is37 mW.S11 and S22 are less than -10 dB.
