High Precision On-chip RC Oscillator: Elevating IoT Device Performance and Integration

Background:

In the Internet-of-Things (IoT) sector, devices need precise timing to communicate effectively and manage power, traditionally achieved using external 32kHz crystal oscillators. While these oscillators are accurate and stable, they add extra cost and require more space, which is a problem for modern, smaller IoT devices. Adding these parts also makes the design and assembly of devices more complex, leading to longer development time and increased manufacturing challenges. This reliance on external components for essential timing functions is a major hurdle in developing more efficient and compact IoT technologies, calling for solutions that integrate these capabilities directly into the device without the downsides of increased cost and complexity.

Description:

Researchers at Northeastern have developed a new type of oscillator for Internet-of-Things (IoT) devices that's built directly into the chip, offering high stability needed for accurate timing. This built-in approach eliminates the necessity for external parts like the traditional 32kHz crystal oscillators and their additional components, leading to smaller and cheaper IoT devices. The key achievement of this technology is its ability to maintain stability within less than 5 parts per million per degree Celsius, matching the performance of external quartz crystal oscillators. This innovation addresses the challenge of keeping IoT devices synchronized and power-efficient, without the added cost and complexity of external timing components. It simplifies the design and production of IoT devices, making it easier to create devices that are both reliable and compact.

Benefits:

• Integration of design leads to a decrease in both device size and manufacturing expenses.
• Precise synchronization enhances device reliability and extends its operational lifespan.
• The elimination of external components offers increased design flexibility for IoT devices.
• Stability on par with quartz crystal oscillators ensures accurate device operation.
• Reduced power consumption makes this technology ideal for battery-operated IoT applications.
