Multirate Sigma-Delta Modulators, an alternative to Multibit the amplifier bandwidth and power consumption, these high-speed, low-power converters operate with a small oversampling ratio, using a unique sampling frequency. This paper shows that multirating is a useful technique to reduce power consumption in high speed SD modulators. To this end, three diffe

High-speed Digital to Analog Converter issues with applications to Sigma Delta Modulatorsbit ΣΔ and Nyquist Converters. The analysis is based on an error-analysis framework, according to which all the errors are classified dependent on their properties with respect to the time and spatial domains. Examples are presented that are related with significant problems occuring during implemen

Sigma Delta Converters in Wireline Communicationsiving applications are presented. Wireline communication products employ Sigma Delta ADCs extensively in voice band modems, ISDN modems and ADSL modems. Especially in the latter ones multi-bit Sigma Delta modulators are used. Design examples for ADSL modems are presented and recent advances, such as

Continuous-time Quadrature Modulator Receivers The low power requirements of the modulator allow it to be integrated into a wireless receiver. An implementation in a 1.57 GHz receiver with a 2 MHz bandwidth is shown. This receiver only needs a SAW filter and a reference cristal as external components.
