Cascode Current-reused Phase linearity Power amplifier (PA) Ultra-wideband (UWB) CMOS technology Link to publisher's homepage at http://ieeexplore.ieee.org/ This letter presents an excellent gain flatness CMOS power amplifier (PA) for UWB applications at 3.0-7.0 GHz in TSMC 0.18 μm CMOS technology. The UWB PA proposed here employs a current-reused technique to enhance the gain at the upper end of the desired band, a shunt and a series peaking inductors with a resistive feedback at the second stage to obtain the wider and flat gain, while shunt-shunt feedback helps to enhance the bandwidth and improve the output wideband matching. The measurement results indicated that the input return loss S11 less than -6 dB, output return loss S22 less than -7 dB, and excellent gain flatness approximately 14.5 ±0.5 dB over the frequency range of interest. The output 1 dB compression of 7 dBm, the output third-order intercept point (OIP3) of 18 dBm, and a phase linearity property (group delay) of ± 178.5 ps across the whole band were obtained with a power consumption of 24 mW. 2010-10-19T07:11:08Z 2010-10-19T07:11:08Z 2010-09 Article IEEE Microwave and Wireless Components Letters, vol. 20(9), 2010, pages 510-512 1531-1309 http://ieeexplore.ieee.org/xpls/abs_all.jsp?=&arnumber=5504002 http://hdl.handle.net/123456789/9890 en Institute of Electrical and Elctronics Engineering (IEEE)
