Integrated ADC for Altera Cyclone-IV Devices
This Technical Brief describes how to use Delta Sigma Modulation to implement resource-efficient Analog-to-Digital Converters (ADC) in Altera FPGA devices. Starting with an introduction into the technology of Delta Sigma Modulation, we will cover the relevant technical aspects for implementing and applying this as a flexible and cost-efficient means for ADC. We will provide the results of diligent testing using Altera Cyclone-IV FPGA devices which led to our technical specifications (Signal-to-Noise Ratios, Linearity, Spurious-Free Dynamic Range values).
