An Auto Ranging Data Converter Implementation in FPGA

A novel project is being presented here for implementation an auto ranging analog to digital converter for biomedical applications completely inside an FPGA - i.e. an all-digital Analog to Digital (A/D) converter system. The only analog part is the auto ranging circuitry and an RC Integrator outside FPGA. The system outputs 24 bits and features a sigma delta ADC of 16 bits resolution, a range detection unit with 7 bits and a sign bit for polarity detection. The analog part of the modulator is done utilizing the LVDS transceiver in the FPGA making it a real digital one.
