Ridgetop’s SMRT Probe (Sample Mode Response Technique™) 4000 is a resonant voltage-sampling sensor that is attached to a module or assembly to extract degradation signatures. Monitoring power systems by injecting a voltage stimulus to measure effective resistance and capacitance, SMRT Probe 4000 provides state-of-the-art prognostic and degradation analysis.
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.
