Opis

The technologically advancements of the chipfabrication and VLSI circuit design have propelledthe concept of a system on chip. The uniquearchitecture of the Delta-Sigma A/DC requiring boththe modulator and the decimation filter on the samechip to reduce the power dissipation has directlybenefited from these developments. The architecturaladvantage of the Delta-Sigma A/DC is itsinsensitivity to process variation allowing forresolution in excess of 20-bit by adjustingoversampling ratio, modulator order, and/or quantizerdimension. Moreover, recently available thin-filmSOI/SOS processes provide excellent potential forcircuit isolation and zero or negligible junctioncapacitors. The 2-3 times lower digital powerconsumption than the bulk processes and higher Qinductors of SOI/SOS attract applications intelecommunication and remote sensing areas, alongwith other applications that depend heavily onmaintaining low power dissipation.
