In the design of a single chip for wireless-sensor-network and WPAN applications (e.g., IEEE 802.15.4), the receiver sensitivity is generally sacrificed in favor of a vanishing power consumption and a low-cost solution. There is a trade off between these two requirements, as the use of resonant loads offers high power efficiency while an inductor-free approach saves die area resulting in a cheaper...
This paper presents an analysis on the receiver front-end architectures for multiband orthogonal frequency-division multiplexing ultra-wide-band (UWB) terminals. An interference analysis is carried out in order to derive the main linearity specifications of the receiver front-end. A reconfigurable narrow-band architecture is introduced that can best cope with the main challenges of the UWB receivers:...
A complete analog front-end, with the exclusion of the frequency synthesizer, for FM broadcasting occupies 2.8 mm2 active area in a standard 0.35 mum CMOS technology. The use of current driven passive mixer and switch capacitor polyphase filter gives +100 dBmuV IIP3, 52 dB adjacent channel selectivity and +39 dB image rejection without trimming or tuning. The output noise is 390 nVparradic(Hz), with...
A GPS RF front-end combines the LNA, mixer, and VCO in a single stage and can operate from a 1.2V supply. The chip is implemented in a 0.13mum CMOS process and occupies 1.5mm2 active area. It consumes 5.4mW with a 4.8dB NF, 36dB gain, and a P1dBof -31dBm
