2002 (English)In: Proceedings of the European Solid-State Circuit Conference (ESSCIRC), Florens, Italy, September, 2002, 351-354 p.Conference paper (Refereed)
An active recursive filter approach is proposed for the implementation of an inductorless, tuned LNA in CMOS. Such an LNA was designed and fabricated ina 0.8 μm CMOS process. In simulation, the feasibility of this type of LNA was demonstrated, and reasonably good performance was obtained. The fabricated device shows a center frequency tuning range from 250 MHz to 975 MHz. Gain and Q value are tunable in a wide range. The LNA exhibits an input referred 1 dB compression point of -31 dB m and a noise figure of approximately 3 dB measured at 900 MHz center frequency.
