Time-interleaved DeltaSigma-DAC for broadband wireless applications.
Written in English
The analysis and design of a time-interleaved delta-sigma digital-to-analog converter (TIM DeltaSigma-DAC) is presented. The digital front-end of the TIM DeltaSigma-DAC comprises a 95th-order time-interleaved-by-8 FIR interpolation filter and a 3rd-order time-interleaved-by-8 DeltaSigma modulator. The time-interleaved architecture uses parallelism to support a low OSR of 8, which results in a large effective bandwidth for broadband applications. The 4-bit output of the DeltaSigma modulator is converted into analog using 16 current-steering cells with continuous current calibration. The chip was fabricated in 90nm CMOS. It was designed to operate at 4GS/s with a bandwidth of 250MHz. The analog back-end was tested with modulated data from a simulation of the digital front-end. It was measured at 2.66GS/s and achieved a bandwidth of 166MHz, an SNR of 46dB and an SFDR of 56dB. At 2GS/s, the prototype consumed 102mW from a 1V supply.

Posted on by puqu. Design of the bit Delta-Sigma Modulator using SC Technique. Abstract: In this paper, we present a single-chip delta-sigma DAC and a class-D amplifier that utilizes internal antialias low-pass filters (LPF). The clock frequency of the delta-sigma modulator is lower than that of the delta-sigma DAC in order to reduce the power loss.

International Journal of Computer Applications ( – ) International Conference on Emerging Trends in Technology and Applied Sciences (ICETTAS ) 20 Delta-Sigma A/D converters now becoming the most suitable solution for standard wireless systems since it is an oversampling converter, delta-sigma modulators can achieve.
Ultra-wideband (UWB) wireless communication is prospering as a powerful partner of the Internet-of-things (IoT). Due to the ongoing development of UWB wireless communications, the demand for high-speed and medium resolution analog-to-digital converters (ADCs) continues to grow.
The successive approximation register (SAR) ADCs are the most powerful candidate to meet these demands.

A Delta-Sigma DAC uses digital techniques to convert a digital number into an analog voltage. Consequently, it is impervious to temperature change, and may be implemented in programmable logic. Delta-Sigma DACs are actually high-speed single-bit DACs.

No delta-sigma DAC really has 24 bit, kHz resolution. To do so would require a sampling rate of about MHz (as they're 1 bit). They're actually quite a bit lower resolution (works out to the equivalent of about 9 bits), and they use noise shapping (ie, cutting the out of band noise from one frequency and pasting it into another, inaudable frequency) so you "don't hear" the difference.
