Arrangement for temporarily disconnecting a circuit block in an integrated circuit

摘要

The invention is used for reducing the power loss of an integrated circuit which is constructed in n-channel technology or p-channel technology and which consists of several circuit blocks. For this purpose, one of the circuit blocks which is temporarily not needed can be disconnected for this time. To effect the disconnection, a blocking circuit (4) is located between the circuit block (1) and the supply line (3) having the lower or higher supply potential. This blocking circuit advantageously consists of an enrichment-type transistor. <IMAGE>
