A tuned wideband LNA in 0.25 /spl mu/m IBM process for RF communication applications

This paper discusses the design of a low noise amplifier tunable over a wide range of frequencies. The LNA is designed for a frequency band 1.4 GHz-2 GHz and provides an output return loss, S22, less than -24 dB, an input return loss, S11, less than -10 dB, a gain of 11.5 dB and noise figure between 1.8-3.4 dB. The LNA has been implemented in 0.25 /spl mu/m CMOS IBM process, with a 2.5V power supply.
