ABSTRACT:
A well-bias system dynamically adjusts well-bias set points to optimal levels across an integrated circuit (IC) for enhanced power savings and component reliability during a standby or low-power mode of operation. A controller within the IC determines if the chip power supply voltage will be reduced during an imminent standby or low power mode and sets a register controlling a negative well-bias set point for asserting well-bias to charge wells of the IC accordingly. To minimize leakage current without compromising reliability, the well-bias set point is set to (1) an optimal well-bias set point if a reduced supply voltage is to be applied to the IC, or (2) a minimum well-bias set point when a nominal or high supply voltage is to be applied to the IC.
