A high integration and low power consumption DAB baseband chip

This paper reports a DAB receiver baseband chip consisting of a DAB baseband decoder and a MPEG L2 audio decoder. The chip complies with European DAB standard Eureka 147 and newly announced Chinese DAB standard GY/T214 2006. The chip was fabricated using standard 0.18 micron CMOS technology and achieved extremely low power dissipation of 30 mW and low gate count of only 100K logic. A DAB receiving prototype was built and the test was carried out. The test results prove that the IC design is successful
