Description
SigmaXplore 6FD is a fully differential, 6th‑order Delta‑Sigma CIFB ADC designed to showcase the more advanced concepts in Delta‑Sigma conversion. This kit features a completely discrete implementation of a high‑order architecture, allowing you to explore the true benefits of multistage Delta‑Sigma design in a hands‑on, intuitive way.
With an oscilloscope, you can examine the system node‑by‑node and observe the dynamics, stability, and behavior of every internal stage—something rarely accessible in high‑performance ADCs. The input accepts a single‑ended 0–3.3 V signal and interfaces directly with a standard PMOD FPGA connector for custom digital signal‑processing workflows.
You can begin with our provided HDL files and expand or refine them as your skills grow. Whether your interests lie in high‑performance audio conversion, instrumentation‑grade measurement systems, or advanced mixed‑signal architectures, SigmaXplore 6FD offers a powerful platform for deep learning and experimentation.
