Example of industrial application: Measurement system

The main challenge for developing an ASIC to interface with a sensor device is to accurate model the sensor device including its interaction with the electronics to be able to predict the MEMS system behavior.

Another main challenge is to ensure the best Return-on-Investment whereas the whole system robustness and yield depend mainly on behavior dispersions of the sensor device which must be taken into account in ASIC design.

Thanks to a deep experience in ASIC and sensor device modeling, Dolphin Integration ensures the stability and yield of the complete system. For ensuring the feasibility and performances, interactions between the sensor device and the electronic part in the MEMS are explored and quantified while the affordable constraints are taking into account. Then, the optimum trade-off is set for meeting economical targets.
