A 60mW baseband SoC for CMMB receiver

This paper describes baseband SoC implementation of China Mobile Multimedia Broadcasting (CMMB) receiver, which integrates analog to digital (ADC), physical layer (PHY) baseband processor and medium access control (MAC) processor in single silicon wafer. MAC functions are fully implemented by firmware on an embedded 32-bit RISC-based processor. In addition, several power management techniques are utilized to reduce the power consumption of baseband SoC. The baseband SoC was successfully fabricated in 0.13μm one-poly six-metal (1P6M) CMOS process. Both analog and digital circuits are integrated on 4.8×4.8 mm² die consuming 60mW total power dissipation under 1.2V and 3.3V supplies. The experiment results reveal the proposed baseband SoC has excellent performance under the multipath channels.
