Innovative Ultra-Miniature Ring Oscillator Temperature Sensor
An important power management functions in commercial IC’s is temperature sensing. Since commercial processors can have as many as 40 sensors, the industry is constantly pursuing a small, low-power sensor.
We present a promising, novel ultra-miniature ring-oscillator sensor which at 750 um2 is the world’s smallest integrated smart sensor and has the one of the lowest energy consumptions.
The Commercial Benefit
Our temperature sensor:
- Is the world’s smallest integrated smart sensor,
- Has an ultra-low energy consumption of 0.1 NJ/conversion,
- Generates a linear temperature dependent frequency which can easily be compared to a reference frequency.
The temperature sensors market is expected to be valued at USD 6.86 Billion by 2023, at a CAGR of 4.5% between 2017 and 2023. The major factors driving growth of this market include the increasing demand for advanced and portable healthcare equipment and the growing automotive sector.
- Automotive sector,
- Healthcare equipment market,
- Consumer electronics market,
- Aerospace & defense industry,
- Food & beverages industry (storage and transportation of food products),
- HVAC systems market.
