Title: Sigma-Delta ADCs and DACs Application Note (AN-283) Author: Analog Devices, Inc. Created Date: 0-01-01T00:00:00Z
Introduction. Digital-to-analog converters (DACs) are usually used as an interface between digital systems and continuous analog circuitry. To choose the type of DAC best suited for an application, the designer must consider many important performance measures.
Sigma-Delta ADCs and DACs. SIGMA-DELTA OVERVIEW. Within the last several years, the sigma delta architecture has become more and more popular for realizing high-resolutionADCs in mixed-signal VLSI processes. Until recently, however, the process technology needed to make these devices commercially viable has not been available.
Summary. Sigma-delta ADC provide trade-offs between: Power consumption, Over-sampling ratio (OSR) System performance (SNR) High OSR implies: Lower number of quantization levels. Lower modulator order, but. More demanding settling requirements for the analog building blocks.
Continuous-Time Sigma-Delta A/D Converters. A/D Converters (ADCs) perform two basic, fundamental operations: discretiza-tion in time and discretization in amplitude. Th e two functions are shown con-ceptually in Figure 1, though the actual ADCmay not be structure as such [ 1 ]. 2 3.
