TL;DR: This paper presents the first published single-chip RF tuner / OFDM demodulator for a mobile digital TV application (1-segment broadcasting) and spurious signal suppression techniques are proposed to improve the minimum sensitivity.
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 90nm CMOS technology and total die size is 3.26mm×3.26mm. By suppressing undesired spurious signals, the minimum sensitivity of −98.6dBm 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 60mW in medium-signal receiving mode.
