Abstract :
We propose in this paper a power adaptive zero-IF receiver based on a wide-band Low Noise Amplifier (LNA) dedicated to wireless home communications operating from 0.8GHz to 11GHz. Two different operation modes (low power consumption mode and high performance mode) controlled by bias conditions are applied to this LNA. The bit rate error (BER) estimated by the Q-factor of eye diagram is used as mean to measure the link quality of receiver. We show that by manipulating the two operating modes of the LNA, the receiver´s power can be reduced at least by 80% under favorable communication scenarios.
