Fast/area efficient 8-bit A/D and D/A designs in 0.8 /spl mu/m cmos technology using layout generators

High performance 8-bit analog-to-digital (A/D) and digital-to-analog (D/A) converters are presented here. To realize the DAC, the advantages of voltage scaling and charge scaling techniques have been combined. For the ADC, a two step "ripple through" A/D architecture which achieves high conversion speeds and area efficiency is presented. Both the A/D and D/A designs were realized using the Mentor Graphics Generator Design Tools (GDT).
