About Us

New Building

Founded in 2000, Ridgetop Group Inc. was established to develop advanced tools, IP libraries, and design services for mission-critical applications operating in harsh environments. Achieving functionality in harsh environments, whether it stems from extreme temperatures or intense radiation exposure, requires "best of class" solutions. These solutions involve "Radiation Hardening" for microelectronics, and/or "Prognostic-enabling" critical systems.

As the firm has grown, commercial firms have also realized the value of engaging Ridgetop design capabilities for less-severe environmental conditions as well. Ridgetop has designed high speed CMOS and SiGe ICs, Digital to Analog Converters (DAC) for MP3 players, to laser range finders.
