Body bias voltage generator - GLOBALFOUNDRIES 22FDX

Overview

The ABX Generator IP is a body bias voltage generator for the ABX Platform for GLOBALFOUNDRIES 22FDX® technology. It contains a closed loop body bias regulation loop to generate N-well and P-well bias voltages for adaptive compensation of process, voltage and temperature (PVT) variations during device operation.
