📄 原文摘要

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. Low-power and low-cost tuner design needs to address both the wideband nature and high dynamic range requirement of a TV tuner which operates across the UHF band (470 to 770MHz) and is subjected to large interferers from other digital and analog TV channels. Also to be able to work properly in cellular phones, good rejection of cellular-band transmit power which is close
