A 1.2V 67mW 4mm2 mobile ISDB-T tuner in 0.13µm CMOS

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 [1]. A low-IF 0.13µm CMOS RF tuner is described to address these challenges.
