Description: A DA converter implemented with fpga, with instructions and source code, VDHL files.
A PLD Based delta-sigma DAC
Delta-sigma modulation is the simple, yet powerful,
Technique responsible for the extraordinary
Performance and low cost of today s audio CD
Players. The Delta-Sigma DAC
Delta-sigma modulator and a one bit DAC. Since,
Both of these components can be realized using
Digital circuits, it is possible to implement a low
precision Delta-Sigma DAC using a PLD.-Using FPGA to achieve the DA converter, has descriptions and source code, VDHL document.
