Abstract

The 1st order single-loop single-bit digital sigma-delta modulator is design in this project.1 bit ADC is use in this project along with Difference Amplifier, integrator and DAC in feedback.2Stage comparator is used as a ADC. Oversampling and Noise shaping technology is use because of this design of anti-aliasing filter also reduce. Furthermore, behavioral simulations of the design are verified using Tanner. A top-down system design methodology that can be used to determine the degree of influence of the modulator structure parameters on the performance of the modulator is provided. This approach not only provides important guiding significance on implement of the modulator in an FPGA processor, but also reduces the design complexity and shortens the integrated circuit(IC) design.
