Abstract :
A 1 V power supply and low-power consumption A/D conversion technique using swing-suppression noise shaping is proposed. This technique makes it possible to power the on chip A/D converter in digital LSI´s directly by a one-cell battery, without a dc-dc converter. Experimental results indicated good performance for the RF-to-baseband analog interface of a digital cordless phone. The A/D converter, fabricated with a 0.5 μm CMOS process, operates on a 1 V power supply, has a 10 bit dynamic-range with a 384 ksps sampling speed and consumes only 1.56 mW
