Abstract :
This paper presents the first published single-chip RF tuner / OFDM demodulator for a mobile digital TV application (1-segment broadcasting). To improve the minimum sensitivity, spurious signal suppression techniques are proposed. The single-chip RF tuner / OFDM demodulator using the proposed spurious signal suppression techniques is fabricated using 90 nm CMOS technology and total die size is 3.26 mm times 3.26 mm. By suppressing undesired spurious signals, the minimum sensitivity of -98.6 dBm is achieved. The optimum current consumption is chosen for the RF tuner by using an adaptive control, the power consumption of the proposed single-chip receiver is only 60 mW in medium-signal receiving mode.
