Abstract :
The widespread use of mobile TV applications has been anticipated in the past few years. In Japan ISDB-T mobile TV service was started in 2006 and within less than 2 years, mobile phones with TV function have become mainstream models. The demand for cost-and power-consumption reduction of RF tuners is very high. In particular, RF tuners consume over 80% of the overall power consumption of an ISDB-T 1-segment receiver, which is composed of RF tuner and digital demodulator. In this paper, a ISDB-T 1-segment RF tuner with low noise figure and high adjacent-channel rejection (ACR) is described. The very low power consumption of 67 mW and compact chip size if 4mm2 are achieved. The tuner operates from a single 1.2 V supply to avoid reliability issues in 0.13mum CMOS, and to simplify the system power supply.
