This paper presents a highly-linear, low power, low noise amplifier (LNA) using a novel nonlinearity cancellation technique by employing the folded cascode topology. The circuit functionality is analyzed using Volterra series analysis. The linear LNA was designed and simulated in a TSMC 0.18µm CMOS process at 5GHz frequency. By employing the new technique, the IIP3 is improved by more than 14dB compare...
A low voltage, low power dual band Low Noise Amplifier (LNA) is presented in this paper. By employing a forward body bias of the MOSFET and current reuse topology the LNA can be operated at reduced supply voltage and power consumption while maintaining high gain due to its topology. Using 0.18 um CMOS process the LNA is designed at 2.4 GHz and 5.2GHz with 13.1 dB and 14.2 dB voltage gains and 2.9dB...
A High Swing Ultra-Low-Power Two Stage CMOS OP-AMP in 0.18 μm Technology with 1.5v supply, is presented.Topology selection and theoretical analysis of the design are discussed. Cascode technique has been used to increase the dc gain. The unity-gain bandwidth is also enhanced using a gain-stage in the Miller capacitor feedback path. The proposed opamp provides 236 MHz unity-gain bandwidth, 81.3 degree...
This paper presents a novel dual-band concurrent fully integrated low noise amplifier (LNA) with current reuse topology for W-LAN IEEE 802.11b/g/a standards. A general methodology for the design of concurrent LNAs is provided that makes it possible to achieve simultaneous narrowband gain and matching at multiple frequencies. Furthermore, the use of a concurrent topology enables saving important die...
