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

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

Correction-Free Multi-Bit Sigma-Delta Modulators for ADSLum resolution losses. The chapter then outlines the dominant circuit imperfections that degrade the operation of this architecture, and presents illustrative design exploration considerations induced by these circuit imperfections. Finally, some practical considerations pertaining to the implementat

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

A Fully Integrated Single-Chip BluetoothTM Transceiverrchitecture with a 4. order complex bandpass filter, 0-48dB variable gain amplifier, 8-bit A-to-D conversion and a fully digital demodulation and clock recovery. In the transmitter, a digital modulator and D-to-A converters generate the baseband signals for a direct upconverter. The quadrature local

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.
