A low power full accuracy MPEG1 audio layer 3 (MP3) decoder with on-chip data converters is proposed. The chip is composed of a digital block to implement MP3 decoding and voice compression/decompression algorithm, 12-bit recycling type A/D converter, and an oversampling /spl Delta//spl Sigma/ 1-bit D/A converter. An efficient power management technique is implemented to reduce power consumption for portable applications. The proposed decoder has been fabricated with a 4 metal 0.35 /spl mu/m CMOS technology and the chip area is about 6.4/spl times/6.7 mm/sup 2/ with 165 mW power dissipation at 2.7 V power supply.
