SWITCHING ARRANGEMENT, INTEGRATED CIRCUIT COMPRISING SAME, METHOD OF CONTROLLING A SWITCHING ARRANGEMENT, AND RELATED COMPUTER PRORAM PRODUCT

摘要

There is disclosed a switching arrangement comprising a switch with a plurality of individually controllable elementary switches connected in parallel between a first supply rail and a second supply rail. Each of the elementary switches can be in either one of a closed state and an open state independently of the others. A controller is adapted to dynamically control the closing or opening of the elementary switches, depending on the intensity of a current flowing through the switch. The number of elementary switches in the closed state is variable. The higher is the intensity of the current, the higher the number of elementary switches in the closed state. Thus, the impedance of the switch decreases when the current increases, and vice versa, and the voltage drop across the switch may be kept substantially constant.
