Chandler, AZ—Startup Stellamar LLC has introduced what they call an innovative, digital-cell-based technology for implementing analog/digital converters in standard ASICs and FPGAs. Using their IP, designers can embed a no-missing-code, oversampling ADC yielding 12-bit resolution and 15-kHz bandwidth, suitable for applications such as data logging, voice, medical instruments, and low-frequency sensors.
The digital core needs only an LVDS input cell, a digital output cell and a handful of passive
external components. The vendor claims their approach reduces time to market and risk significantly, while also decreasing cost and silicon footprint by 50%.SNR at 4 kHz is 72 dB and 68 dB at 15 kHz. The IP has been built and evaluated with a Xilinx Spartan FPGA, see figure.—Bill Schweber
