Adaptive Body Biasing Generator - GLOBALFOUNDRIES 22FDX

Overview

RI_ABB_GF22FDX is a body bias voltage generator for the Racyics® ABX® adaptive body biasing (ABB) foundation IP 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.

Key Features

Integrated adaptive body bias (ABB) control loop
Charge pumps for N-Well and P-Well voltages, operated from IO supply voltage level
Integrated PVT monitors for true independent adaption of NMOS and PMOS performance
Operation from typically 10MHz, up to 50MHz reference clock
Available in forward (FBB) and reverse body bias (RBB) versions
Available in multiple charge pump drive strengths supporting a wide range of active chip areas
Delivered as hardmacro for easy and seamless integration
Supports dynamic bias corners down to 0.40V nominal.
Interoperable with foundation IP standard cells and SRAM
