Adaptive Body Biasing IP

• RI_ABB_GF22FDX_AM is an adaptive body bias voltage generator for automotive applications in Globalfoundries 22FDX® technology.
• It contains a closed loop body bias regulation loop to generate N-well and P-well bias voltages for compensation of process, voltage and temperature (PVT) variations during operation.
• This results in up to 76% leakage power improvement for automotive grade-1 applications up to 150°C junction temperature.

• ABB generator, standard cells, SRAM
• Up to 9X performance
• 75% leakage reduction

• Single port SRAM compiler based on Racyics® R188 logic memory cell with dual-well architecture
• Supply voltage 0.55 V to 0.8 V enabled with Racyics® ABB

• Single port SRAM compiler based on P124 bitcell with Dual-supply-rail architecture
• Bitcell array supply voltage 0.8V and ULV core interface down to 0.4V enabled with Racyics' ABB
