Low-frequency noise reference centre chosen by Keysight for EMEAI

The Fraunhofer Research Institution for Microsystems and Solid State Technologies EMFT (Fraunhofer EMFT) is the first low-frequency noise measurements reference centre able to demonstrate the Keysight Technologies EEsof EDAs E4727A Advanced Low-Frequency Noise Analyser in Europe, the Middle East, Africa and India (EMEAI).

Fraunhofer EMFT is one of the leading research centres enabling the creation of sensor solutions to meet the strong demand for better and versatile sensors, driven by markets such as the Internet of Things (IoT). The main limiting factor in CMOS sensors is the low-frequency noise, and therefore the accuracy needed for noise measurements has dramatically increased.

The continuous improvements required to scale down electrical nodes associated with the ongoing quest of reducing the power consumption of sensors has dramatically increased the influence of low-frequency noise.

In addition to flicker noise, the importance of reliable measurements of random telegraphic noise (RTN) is even more crucial.

Moreover, recent materials such as organic semiconductor or gallium nitride (GaN) are using, among other techniques, the low-frequency noise measurements as a way to understand some material effects.

After introducing its E4727A low-frequency noise system, Keysight has decided to partner with renowned research centers in the field of noise measurements, Fraunhofer EMFT is the first selected to host customers that are interested in seeing the E4727A capabilities.

“Using the Keysight state of the art technology available in low-frequency noise measurements software further extends the quality of our sensors noise measurements. This is enhanced by the on-wafer automation and very low noise floor capabilities. The start frequency of 30 milliHertz helps to identify RTN (Random Telegraph Noise) areas that were previously difficult to uncover,” said Professor Dr. Ignaz Eisele, Head of Sensors and actuators division at Fraunhofer EMFT. “We also look forward to making available this capability to Keysight customers at our facility.”

“Low-frequency noise has become a major field of research worldwide, covering areas such as reliability, material quality and improvement of key integrated circuits, such as CMOS sensors or memories,” said Cédric Pujol, EMEAI Device Modeling business development manager for Keysight EDA.

“Working closely with Fraunhofer EMFT is perfectly aligned with Keysight’s commitment to strengthen our collaboration with leading research centers in Europe, the Middle East, Africa and India” said Benoit Neel, vice president and general manager, EMEAI field operations at Keysight.
