Abstract :
An ISDB-T 1-segment RF and BB chipset with adaptive bias-current control is presented. The BB IC monitors MER and dynamically sets the bias current of RF sub-circuits. In the worst reception case, the chipset consumes 105mW. In the absence of strong interferences, the adaptive control reduces the consumption down to 77mW without performance degradation.
