Adaptative Body Bias IP, the missing piece to achieve ultimate energy efficiency in 22FDX

Conscious of the booming of AI, IoT, mobile and automotive products in the industry, we are committed to accelerating the development of energy-efficient System-on-Chip (SoC) for our customers. In the race for higher energy efficiency, digital designers face the impact of variations, which modify the actual chip specifications defined by the extreme variations cases. To cope with those variations and optimize the energy efficiency, SoC designers often use compensation techniques.

Through the control of transistor threshold voltage in FD-SOI technology, body bias acts as a fantastic control knob to offset all variations. Designers can design their SoCs with reduced design corners for process, voltage and  temperature boosting the Power-Performance-Area trade-off.

We have been cooperating with GF over the last two years to provide a revolutionary Adaptive Body Bias (ABB) IP enabling real time control of transistors threshold voltages. Our all-in one ABB IP features a bias generator, low power sensors, and a control loop to enable  on-the-fly  adaption of transistor threshold voltages in reverse and forward modes.

Adaptive body bias IP is the 1st industrial turnkey IP compatible with all 22FDX foundation libraries enabling designers to realize the full benefit of FD-SOI for any SoC design.  A new level of power, performance and reliability can now be achieved. Up to 10x speed improvement on an ARM® Cortex®-M4 based on GLOBALFOUNDRIES 22FDX has been proven on silicon at low VDD.

This new solution simplifies design implementation, shortens product time-to-market, paves the way to future performance standards in 5G, IoT and automotive. The ABB IP version targeting ULP IoT & middle performance SoC is now available for volume production in 22FDX technology.
