Zusammenfassung:Systems and methods for circuits with substantially equal propagation delay while providing different drive strengths are disclosed. These systems and methods may allow for a circuit with a drive strength that is some ratio of an arbitrary strength full drive strength circuit. Additionally, these circuits may have substantially the same input capacitance and feedback current as the baseline drive circuit. The input of such a circuit may be coupled to three nodes, one of which is an inverter coupled to the logic to be driven, the second of which is dummy logic, and the third of which is an inverter the output of which is left floating.
