Ultra-Low Power Microelectronics

Ultra Low Power Electronics

Modulus' expertise in the design of ultra-low power embedded systems has been successfully applied to the development of devices including implantable devices and scuba diving computers. In addition to ultra-low power circuit and system design, we have an equally mature process for embedded firmware development. Once design is completed, our electronic engineers and firmware designers start with developing the system architecture for the product, and begin prototyping the system. We generally develop several prototype circuit boards to support firmware development. Since most scientific instruments are battery operated, we help in the selection and qualification of appropriate battery systems.

We have developed a product prototyping system that allows us to optimize different functional blocks of the system, such as sensor interface, RF communications, display, and power management. By taking this modular approach to rapid prototyping, we not only optimize the hardware design, but also create a similar modular approach to firmware design. The breadboard prototypes are then evaluated by customers for function and the design is iterated as required. In some cases, we have completed the system architecture and hardware design and prototype development, and our customer has done all the firmware design.

Verification and validation of software and firmware is simplified by our modular design philosophy. Modulus has standardized and optimized the design of several common building blocks, such as MICS radio transceivers and power management approaches. This ensures that our designs are robust, testable and verifiable.
