Simplified Logic for First-Order and Second-Order Mismatch-Shaping Digital-to-Analog Converters
Mismatch-shaping digital-to-analog converters (DACs) have become widely used in high-performance delta–sigma data converters because they facilitate delta–sigma modulators with multibit quantization. Relative to single-bit quantization, multibit quantization significantly relaxes the analog circuit performance necessary to achieve a given level of data converter precision, but significant digit...
متن کاملReducing multibit DAC circuits errors by a simplified dynamic element matching algorithm used in delta-sigma converters
Resolution of a multibit delta-sigma modulator (DSM) is limited by its internal digital-to-analog converter (DAC) nonlinearity that is usually caused by circuit mismatch errors while realizing. Recently, some dynamic element matching (DEM) methods were proposed for reducing mismatch errors. Two main difficulties of different dynamic element matching (DEM) techniques relate to instability and co...
متن کاملDesign of a Power/Performance Efficient Single-Loop Sigma-Delta Modulator for Wireless Receivers
In order to design high performance sigma-delta A/D converters, it is essential to estimate the Figure-Of-Merit in the design process. This paper describes the design of a power/performance efficient single-loop multibit sigmadelta modulator for wireless applications. Power dissipation is minimized by optimizing the architecture and by a careful design of analog circuitry. A 3 order 4-bit Σ-∆ m...
متن کاملA 50-MHz Multibit Sigma–Delta Modulator for 12-b 2-MHz A/D Conversion
Oversampling techniques offer several advantages for the implementation of high-resolution analog-to-digital (A/D) converters in VLSI technologies. This paper examines the application of oversampling techniques to A/D conversion at rates exceeding 1 MHz. A cascaded multibit sigma-delta (2A) modulator that substantially reduces the oversampling ratio required for 12-b conversion while avoiding s...
متن کاملHigh-Speed Multibit Delta-Sigma ADCs with On-Line Digital Error Correction
Multibit delta-sigma modulators are widely used in recent analog-to-digital converter (ADC) implementations [1, Chapter 8]. Due to their improved stability, they can achieve the same high signal-to-noise ratio (SNR) with lower order modulator and lower oversampling ratio (OSR), i.e. higher speed, than their singlebit counterparts. Also, the use of a multibit feedback relaxes slew-rate and settl...
