0.18 μm CMOS RF front-end chipset for FM-UWB based P-PAN receivers

This paper describes the design and implementation of a fully differential RF front-end chipset for a low data rate FM-UWB based P-PAN receiver. The chipset includes an ultra-wideband LNA and a wideband RF demodulator. A 0.18 mum standard CMOS RF process is chosen as the technology vehicle. Measurement and demodulation function verification are presented in the paper. The measurement results show that the presented chipset are able to receive and demodulate FM-UWB RF signals successfully. The chipset achieves a 2.2 GHz (2.3 GHz-4.5 GHz) bandwidth, 2.6 GHz-4GHz carrier frequency and an overall average noise figure of 7 dB. The total current consumption by core circuit is around 6.36 mA using a 1.8 V DC power supply.
