ETA - Universal Energy Harvesting System

ETA platform is the 1st set of silicon IPs specifically designed for energy harvesting, ultra low power and sensor based applications. Integrating harvesting block, dedicated power management, configurable analog front-end with ADC and programmable task manager, ETA is a unique solution in the market conceived to meet the most demanding and advanced performance needs in complex low energy budget applications.
Wherever a signal should be conditioned and monitored with stringent power consumption constraints, the ETA overcomes power budget limitations extracting useful energy from the environment sources and performing in the most efficient way repetitive and frequent tasks in complete autonomy.
