Feedback stage for protecting a dynamic node in an integrated circuit having dynamic logic

摘要

An integrated circuit having dynamic logic (20) is disclosed that includes a dynamic node (NODE 1). A feedback stage protects the dynamic node (NODE 1) and includes a controllable current path (26) connected between a voltage supply and the dynamic node (NODE 1), where the controllable current path (26) has a control terminal. The feedback stage also includes a feedback path from the dynamic node (NODE 1) to the control terminal, where the feedback path includes a delay stage (27) providing a delay greater than intrinsic circuit delay.
