Ridgetop Group offers a range of digital-to-analog converter (ADC) intellectual property (IP) blocks, including radiation-hardened blocks. Architectures includes delta-sigma and current steering.
RG16100: DAC 16-BIT, 100 KSPS, TSMC 250 NM IP CORE
Ridgetop’s audio DAC uses delta-sigma architecture. As shown in the illustration above, the DAC uses a digital interpolation filter, a digital second-order delta-sigma modulator, and a 32-tap analog reconstruction filter FIR. A fourth-order modulator is available to decrease oversampling ratio if the application requires. Applications for this core include audio commercial electronics, industrial control, and automotive.

Ridgetop is certified as category 1A under the Defense Microelectronics Activity (DMEA) as part of the Trusted Supplier Program. Ridgetop has history of designing analog and mixed signal ICs for demanding applications in space satellites that are subjected to extreme temperatures and radiation. Our designs have utilized bulk CMOS, CMOS-SOI, and SiGe at process geometries down to 28 nm channel lengths. Radiation hardness is also a concern, and Ridgetop has addressed those requirements as well. A recent Ridgetop design was delivered to ON Semiconductor for the U.S. Air Force STELLAR Star Tracker.
Under contract to NASA, Ridgetop designed an effective 3-axis wireless rotational sensor. The RotoSense™ sensor has been tested on fast-spinning pinion gears on helicopter gear boxes, and also rolling stock for railroad safety improvements.
