Yoshida, K. sohiful@unimap.edu.my murad@yossvr3.ed.kyushu-u.ac.jp Current-reused Power added efficiency Power amplifier Ultra wideband Link to publisher's homepage at http://ieeexplore.ieee.org/ This paper describes the design of 3.1 to 4.8 GHz CMOS power amplifier (PA) for ultra-wideband (UWB) applications using 0.18-m CMOS technology. The UWB PA proposed here employs cascode topology with a currentreused technique to enhance the gain at the upper end of the desired band, an inter-stage inductor, and a resistive feedback at the second stage to obtain the flatness gain. The measurement results indicated that the input return loss (S11) was less than -5 dB, output return loss (S22) was less than -8 dB, and average power gain of 10.3 dB with a flatness about 0.8 dB. The input 1 dB compression point about -2 dBm and excellent phase linearity (group delay) of ± 135 ps across the whole band were obtained. Moreover, a very high power added efficiency (PAE) of 40.5% at 4 GHz with 50Σ load impedance was achieved with a power consumption of 24- mW. 2011-01-12T02:54:00Z 2011-01-12T02:54:00Z 2010-08 Article IEEE Transactions on Consumer Electronics, vol. 56(3), 2010, pages 1241-1246 0098-3063 http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=5606253 http://hdl.handle.net/123456789/10461 en Institute of Electrical and Electronics Engineers (IEEE)
