Abstract
A contention-free keeper circuit including a keeper circuit having a first node and a second node, is provided. The contention-free keeper circuit may further include a delay element for providing time delay. The contention-free keeper circuit may further include a high-to-low contention element coupled between the first node and a first supply, and coupled to the delay element output. The contention-free keeper circuit may further include a low-to-high contention elimination element coupled between the first node and a second supply, and coupled to the delay element output, (i) wherein responsive to a low-to-high transition at the first node and the time delay, the low-to-high contention elimination element eliminates a low-to-high contention within the keeper circuit, and (ii) wherein responsive to a high-to-low signal transition at the first node and the time delay, the high-to-low contention elimination element eliminates a high-to-low contention within the keeper circuit.
