Adaptive control of power supply for integrated circuits

摘要

The present invention relates to a circuit arrangement and method for controlling power supply in an integrated circuit wherein at least one working parameter of at least one electrically isolated circuit region (10) is monitored, and the conductivity of a variable resistor means is locally controlled so as to individually adjust power supply for each of said at least two electrically isolated circuit regions (10) based on the at least one monitored working parameter. Thereby, a fast and simple control functionality with low area overhead can be provided.
