Selecting optimized ESD protection for CMOS image sensors

Today, you can find CMOS image sensors almost everywhere in consumer, automotive, health and security applications. There has been a lot of innovation to enable demanding requirements.

The article provides a summary about the 3 main aspects that IC designers need to consider when selecting the ESD protection clamps for their image sensor projects.

3 approaches to handle EOS ‘requirements’

EOS, or Electrical Overstress, is any electrical stress that exceeds any of the specified absolute maximum ratings (AMR) of a product.

It is important to discuss because many products are damaged this way.

This article includes case studies and 3 approaches to handle those requests.

Optimized on-chip ESD protection to enable high-speed Ethernet in cars.

In the past most Electronic Control Units (ECU) used CAN and LIN interfaces to connect to sensors, actuators and each other. However, the newest applications need (much) faster communication options. Gigabit automotive ethernet is pushed by many in the industry as the perfect solution.

With its local ESD clamp approach, Sofics provides the best solution to protect those high-speed chip interfaces against Electrostatic Discharge events.
