Abstract :
The proposed circuit of a monolithic band-pass Low-Noise-Amplifier (LNA) provides on 0.8 μm BiCMOS (17 GHz NPN) a gain of 35 dB at 3 GHz and need only 8 mW from low-voltage power supply (2V). It is built using a common-base stage followed by a modified White´s cascode, both employing low-Q inductors on-chip. The central frequency can be pre-tuned within ±10%, and the gain pre-set independently within 20 and 40 dB. The circuit is suitable for use as amplifier-filter-buffer in various wireless communications units
