Design of Folded-Cascode Low Noise Amplifier with low power and high gain for UWB application

ABSTRACT: This paper presents the low noise amplifier for ultra wide-band applications.the UWB LNA is design in ۰.۱۸µm 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 ۱۲.۷ dB and minimum noise figure of ۲dB is achieved. The total power consumption is۳۷ mW.S۱۱ and S۲۲ are less than -۱۰ dB.
