The PA design employs two stages cascade with inductive peaking technique to provide broad bandwidth characteristic and higher gain while gain flatness can be achieved by connecting inter-stage circuit. A common gate current-reused technique is adopted at the first stage amplifier to achieve good input matching, low group delay and low power. The simulation results show that the proposed PA design has an average gain of 11.5 dB with flatness of ±0.4 dB from 5-11 GHz, while maintaining bandwidth of 4.2-12.3 GHz. An input return loss (S 11) less than -10.4 dB and output return loss (S 22) less than -9.5 dB, respectively are obtained. The PA design achieves excellent phase linearity (i.e., group delay variation) of ±41 ps and only consuming 17 mW power from 1.2 V supply voltage. A good output 1-dB compression point OP1 dB of 3.7 dBm is obtained. By using this method, the proposed design has low group delay variation and lowest power among the recently reported UWB CMOS PAs applications 2014-01-29T08:48:22Z 2014-01-29T08:48:22Z 2012-11 Article AEU - International Journal of Electronics and Communications, vol. 66(11), 2012, pages 928-932 1434-8411 http://www.sciencedirect.com/science/article/pii/S143484111200088X http://dspace.unimap.edu.my:80/dspace/handle/123456789/31600 en Elsevier GmbH
