Abstract

An integrated circuit (10) comprises a plurality of functional blocks (101, 102, 103), each of the functional blocks (101, 102, 103) being coupled between a first power supply line (110) and a second power supply line (120). A first functional block (101) is coupled to the first power supply line (110) via a first conductive path including a first switch (131) and a second functional block (102) is coupled to the first power supply line (110) via a second conductive path including a second switch (132), the first switch (131) and the second switch (132) being arranged to respectively disconnect the first functional block (101) and the second functional block (102) from the first power supply line (110) for switching said functional blocks (101, 102) from an active mode to a standby mode. The IC (10) comprises a further switch (141) having a first terminal coupled to a node (121) of the first conductive path between the first switch (131) and the first functional block (101) and a second terminal coupled to a node (122) of the second conductive path between the second switch (132) and the second functional block (102). The further switch (141) has a control terminal responsive to an…
