Abstract

This brief presents a highly integrated low-Intermediate Frequency receiver for use in UHF/VHF channel 7 and Channel 8 Integrated Services Digital Broadcasting-Terrestrial (ISDB-T) systems (90-220 MHz). It features an ultralow power consumption of 68 mW (55 mW in attenuator mode) with a noise figure of 3 dB. The device fully complies with the ISDB-T standard and is implemented in 0.13-μm CMOS technology with fully integrated low-noise amplifier/matching networks, a voltage-controlled oscillator, a phase-locked loop/loop filter, a crystal oscillator, baseband filters, and Variable Gain Amplifier. The tuner only requires a prefiltering RF surface acoustic wave filter to notch out cellular frequencies and a biasing inductor to implement a fully compliant ISDB-T tuner. The full characterization of the tuner and the comparison with previous implementation are presented. The chip area is 2.1 mm × 2.1 mm.
