A multi-mode multi-band CMOS direct-conversion mobile-TV tuner for DVB-H/T and T-DMB/DAB applications

Abstract

A fully integrated direct-conversion mobile-TV tuner for DVB-H/T and T-DMB/DAB applications was fabricated using 0.18 um CMOS process. This tuner has the good SNR and immunity performance over wide dynamic range for multi-band and multi-mode applications with the automatic gain control and calibration schemes. The power consumption is 127 mW for VHF and UHF, and 135 mW for L-band at 1.8 V supply voltage.
