Abstract :
Two array antennas and one carrier diversity combiners are integrated with Japan Terrestrial digital TV (ISDB-T) OFDM receiver using 90 nm 7M1P CMOS process. A 2/4/8 antennas diversity receiver can be configured and the low cost 4 antennas diversity reception system can be realized by one LSI. The mobile reception performance is increase by 63% using de-noise filter circuit and SPLINE interpolator. The die area is 49 mm2 and the power consumption is 310 mW.
