This paper presents an inductor-less low-noise amplifier (LNA) design for ultra-wideband (UWB) receivers and microwave access covering the frequency range from 0.4 to 5.7 GHz using 0.18-μm CMOS. Simulation results show that the voltage gain reaches a peak of 18.94 dB in-band with an upper 3-dB frequency of 5.7 GHz. The IIP3 is about -3 dBm and the noise figure (NF) ranges from 3.15-3.86 dB over the...
The ever increasing global space activity is characterised by emerging space systems, operation and applications challenges. Hence, reliable RF and microwave receivers for in-orbit highly adaptive small satellites are needed to support reconfigurable multimedia/broadband applications in real-time with optimal performance. Though other parameters of the small satellite communication system may be critical,...
Impulse-radio ultra-wideband (I-UWB) systems for sensing and communications offer very low power consumption, and allow precise radar and location sensing alongside with communications. Therefore, they are interesting candidates for medical applications. This paper reports on the development of a complete I-UWB chipset, consisting of pulse generators, low-noise amplifiers, and correlators aiming at...
This paper describes one of the first dual PCS- and CEL-band CDMA receivers that includes LNAs and VCOs on a single die. The PCS-band LNA achieves a noise figure (NF) of 1.5dB and IP3 of +7.5 dBm at 16-dB gain. The PCS demodulating mixer achieves an NF of 5 dB, IP3 of +5 dBm and uncalibrated IP2 of +60 dBm. The PCS VCO is capable of -134 dBc/Hz phase noise at 3.9 GHz and 1.25-MHz offset. A copper...
