A 3-5GHz frequency tunable ultra wideband LNA for OFDM applications. Gong, F., Lam, K., Ismail, M., Park, S., & DeGroat, J. In Midwest Symposium on Circuits and Systems, 2009. abstract bibtex In this paper, a frequency tunable differential input differential output Low Noise Amplifier (LNA), used for 3-5GHz OFDM applications, is proposed and analyzed. The LNA has a wideband input matching and a tunable output matching. The digital controlled capacitor arrays in the output matching networks allow the LNA to be switched smoothly in the frequency range of 3 to 5GHz with output return loss less than -15dB. The overall LNA is designed with TSMC 0.18 μm technology, and the simulation result shows that the input return loss is less than -12dB and the noise figure is less than 4.5dB in desired frequency range. At 3.3V power supply, the LNA achieves an 8-12dB transducer gain in the frequency range with the power consumption of only 20mW. © 2009 IEEE.
