Sofics is the world leader in IP for robust IC design. Its patented technology is proven in more than 3000 IC designs across all major foundries and process nodes. IC companies of all sizes rely on Sofics for off-the-shelf or custom-crafted solutions to protect analog IOs, overvoltage IOs, high speed, high frequency or other non-standard IOs, and high-voltage ICs, including those that require system-level protection on the chip for ESD, EOS, EMC, radiation or other specifications.


Sofics technology produces smaller solutions than any generic, conventional ESD configuration. It also permits twice the IC performance in high-frequency and high-speed applications. Sofics solutions and services begin where the foundry design manual ends.


IP Provider

Sofics licenses IP to improve the robustness of ICs in the most cost-effective way, without jeopardizing functionality. Currently this is offered in 3 IP portfolio

TakeCharge  – ESD/EOS/Latch-up protection for low voltage (up to 5V) and mature/advanced processes (0.18um down to 16nm)

PowerQubic –  ESD/EOS/Latchup protection for high voltage (up to 100V) and BCD processes

CustomIO – Circuit solutions, including IO’s, clipping circuit for Antenna applications, ….

IO Design

IO’s beyond the standard offering, made available in any CMOS/SOI/FinFET technology. In many cases the analog or digital IO’s are targeted to pass difficult robustness specs.

  • High ESD (HBM/MM/CDM)
  • High system level on-chip (IEC 61000-4-2)
  • High EOS (IEC 61000-4-5)

IP Cores

Low Voltage ESD/EOS protection (up to 5V)

Organized in the  TakeCharge IP portfolio, Sofics offers a wide range of ESD/EOS/latch up solutions, silicon proven in a variety of CMSO/SOI/FinFET processes (for a full list). Porting to another process is always possible.


The solutions are optimized for cost, robustness and performance:

  • Cost: save on silicon cost (small area), time to market, and mask sets
  • Robustness: any standard (HBM, MM, CDM, IEC 61000-4-2, IEC 61000-4-5, JEDEC78, …), any level
  • Performance: low capacitance (down to 10fF!), low leakage, overvoltage tolerant, …


HV/BCD EOS/ESD protection (5V and higher)

Sofics’ PowerQubic IP portfolio offers ESD/EOS/Latch up/EMC solutions for HV and BCD processes.

The solutions are tailored for demanding applications, such as automotive, industrial or medical.

Specifications include

  • On-chip ESD HBM/MM/CDM
  • System level ESD on-chip (IEC 61000-4-2, ISO 10605)
  • Automotive disturbances (ISO 7637-2 & -3)
  • EMC specifications (IEC 62312, ISO 11452)

LIN PHY (transceiver)

Automotive interfaces can be challenging to design, due to a large set of reliability specifications, such as EMC or automotive disturbances such as described in ISO 7637.  Sofics has predeveloped a LIN transceiver (PHY) for 12V batteries, conforming to the LIN specification document (ISO 179870), including driver, ESD protection, EMC protection etc. (LIN controller not included)


The PHY can be ported to any process. Visit our LIN page for more information.


Other automotive interfaces are under development. Contact us if you want more information!

Programmable Clipping Circuit for Antenna pins

A clipping circuit to limit the voltage of input signals coming from an antenna pin. The clipping voltage can be selected (currently 2 options) or disabled.

The circuit is product proven for NFC applications in TSMC 65nm, but can be ported to any desired process.
