Adaptive Body Biasing Generator - GLOBALFOUNDRIES 22FDX

RI_ABB_GF22FDX is a cutting-edge adaptive body bias (ABB) generator for GLOBALFOUNDRIES® 22FDX® technology. Featuring patented closed control loops with independent N-well and P-well body bias voltage generation, this silicon-proven IP dynamically compensates for process, voltage, and temperature (PVT) variations during operation.
