چکیده
This paper presents a ultra wideband low noise amplifier for 6GHz Applications. This proposed LNA is the extension of inductively common source amplifier and in this design we used transistor multifingering techniques in order to reduce noise and improves gain. This LNA is simulated by using UMC .18um CMOS mixed signal/RF process in cadence virtuoso. In this design, used current source biasing, with power supply is 1.8v. LNA achieved gain 19dB and noise figure is 1.8dB at operating frequency range, and input & output return losses are -24dB & -15dB respectively, reverse isolation is -36dB and stability is 4, IIP3 is -10dBm, 1-dB compression point -17dBm and total power consumption is 9mw. Keywords—cascode source degeneration amplifier, current mirror, low noise amplifier, de-Q resistor, multifingring Techniques.

A New Ultra-Wideband Low Noise Amplifier With Continuous Gain Control
This paper presents a new variable gain low noise amplifier (VG-LNA) for ultra-wideband (UWB) applications. The proposed VG-LNA uses a common-source (CS) with a shunt-shunt active feedback as an input stage to realize input matching and partial noise cancelling. An output stage consists of a gain-boosted CS cascode and a gain control circuit that moves the high resonant frequency to higher freq...
