As technologies and their power supply voltages scale down, it becomes
more difficult to maintain the accuracy of data converters. At the
same time, increasing complexity of systems on chip demands data
converters with lower power consumption and higher accuracy. We are
investigating a variety of techniques such as predistortion
and self calibration to lower the power consumption and improve the
accuracy.
