Optimized Local I/O ESD Protection for SerDes In Advanced SOI, BiCMOS and FinFET Technology

Sofics’ 2021 IEDS publication.
Semiconductor companies are developing ever faster interfaces to satisfy the need for higher data throughputs. However, the parasitic capacitance of the traditional ESD solutions limits the signal frequency. This paper demonstrates low-cap Analog I/Os for high speed SerDes (28Gbps to 112Gbps) circuits created in advanced BiCMOS, SOI and FinFET nodes.

New opportunities for automotive LIN interfaces

Due to the semiconductor shortage in 2021 everyone realized that cars these days integrate a lot of electronics. The average number of computer chips per car has increased a lot in the last decade.

It is clear that the new applications require high-speed interconnects that are not possible with the initial, low-speed interface types. But there is also innovation possible for the old interface types like LIN/CAN by combining it together with other IP blocks on a single die.

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.
