Abstract
Adaptive regulated power supply voltages are applied to programmable logic integrated circuits. Control circuitry in a programmable logic IC generates control signals that are transmitted to an external voltage regulator. The voltage regulator generates one or more power supply voltages in response to the control signals. The values of control signals determine the target values of the supply voltages. The control circuitry can adapt the power supply voltages to compensate for temperature and process variations on the IC. The power supply voltages can be programmed by a manufacturer or by a user to achieve desired target values. The control circuitry can also put a programmable logic IC into a sleep mode by dropping the high supply voltage to a low value to reduce power consumption during periods of low usage.
