The technologically advancements of the chip
fabrication and VLSI circuit design have propelled
the concept of a system on chip. The unique
architecture of the Delta-Sigma A/DC requiring both
the modulator and the decimation filter on the same
chip to reduce the power dissipation has directly
benefited from these developments. The architectural
advantage of the Delta-Sigma A/DC is its
insensitivity to process variation allowing for
resolution in excess of 20-bit by adjusting
oversampling ratio, modulator order, and/or quantizer
dimension. Moreover, recently available thin-film
SOI/SOS processes provide excellent potential for
circuit isolation and zero or negligible junction
capacitors. The 2-3 times lower digital power
consumption than the bulk processes and higher Q
inductors of SOI/SOS attract applications in
telecommunication and remote sensing areas, along
with other applications that depend heavily on
maintaining low power dissipation.
