Startup funded for timing compensation

Business news |
Fabless IC design startup SemiBlocks BV (Eindhoven, The Netherlands) has raised €3 million (about $3.5 million) for its mission to develop CMOS circuits to compensate for hysteresis and frequency errors due to temperature variation in crystal oscillators.

The SemiBlocks solution works with a low-cost crystal. No further external components are required enabling integration in other functions, the company said. Applications range from consumer products such as smartphones and tablets to mobile network infrastructure.

SemiBlocks was founded in 2017 and has raised the money from BOM Brabant Ventures and an unnamed strategic partner in the US. Conventional communication products use a variety of temperature compensation methods to maintain frequencies and communication channels and SemiBlocks expects to make an initial contribution in 4G/5G basestations.

“There are many problems with these conventional products, e.g. limited accuracy, high costs, and limited temperature range,” said Rob van der Valk, CTO and co-founder of the company. “SemiBlocks has developed a disruptive technology solving these problems using standard IC design technology. It plans to be the first company to introduce a self-sensing measurement system enabling the use of low-cost materials while achieving higher accuracies. Other advantages are the support for a much larger temperature range and the option for further integration into other ICs.”

The technology is patented and applicable to telecommunications infrastructure, data centers and smartphone and tablet platforms.

SemiBlocks said it expects to launch its first product for small basestations in 4G/5G radio communications market early 2020.
