Design of high-speed analog-to-digital interface in digital technologies

Analog design in deep sub-micron digital technologies is a reality now and poses severe challenges to the circuit designer. Trends in digital technologies as well as their effects on analog circuits axe discussed. The typical speed-power-accuracy trade-off in analog design is revised with respect to the technological modifications. A new speed model includes slew rate behaviour together with settling behaviour. Calculations show a possible increase in power for future generations of high speed analog-to-digital converters.
