• We describe low supply voltage analog circuit techniques for voice- and audio-band interfaces. These techniques can lower the supply voltage to 1 V, which is the voltage of a one-NiCd-cell battery. We have applied them in a swing-suppression noise-shaping method, and using this method, have fabricated A/D and D/A converters for the voice and audio bands. These converters operate with a l V power supply and have 13-bit and 17-bit accuracy in the audio-band and power consumption of about 1 mW. This performance proves that our techniques are sufficient for baseband analog interfaces. key words: low-voltage analog, A/D converter, D/A converter swing-suppression noise-shaping
