Abstract
An anti-charge share device and method for operation ensure that charge share protection is provided for nodes in a logic circuit during an evaluate stage with low costs in terms of power and circuit performance. The anti-charge sharing device includes a transistor coupled between pre-charge node and a second node being evaluated. By coupling the charge share device between the pre-charge node and the node to be evaluated, operation of the charge share device is dependent upon a node which no longer requires a charge-sharing protection.
