Excitation and Processing for Sensors
Sensors are originating from research which often have a complex excitation and processing of just the same complexity. In many cases, as soon as research is finished, the sensor works and control of the sensor is clear the electronics can be optimized for performance and price towards the first product. Even though the optimization is concentrated on price, often through the omission of analog electronics the solution gets more stable and is more easily manufactured.
Through our co-design of electronics and digital signal processing in the software we could achieve simple cost-effective solutions which allowed a fast product launch. A rapid prototype of the new architecture allowed the validation of the concept and the minimization of the risks for the development to a product.
Expertise and Technologies
The rapid prototypes are based on specialized signal processors or on ARM-Cortex cores with the according arithmetic units (e.g. Cortex-M4F). Added to this are the customized input and driver stagesfor the sensors, in one case high temperature components up to 200 °C where designed in.
Through the fast understanding of the specific measurement principle, its simulation in MATLAB and a clear system design, improvements of the overall system performance could be achieved.
