Abstract
Sigma-delta modulator based digital-to-analog converters (DAC) have offered low-frequency designers a highly
linear, high resolution data converter architecture that is highly amenable to integration with complex digital systems.
Increasingly these data converters have been used to deliver all the power needed. In wireless applications, it is increasingly desirable to apply low-frequency sigma-delta techniques to RF signals and try to achieve similar benefits. In this paper we discuss the unique challenges that DACs in mobile phone basestations must satisfy and we present a flexible bandpass sigmadelta
modulator architecture that can satisfy these criteria.
