Abstract:
Circuits and methods for delay mismatch compensation are described. A circuit may comprise multiple data paths between a signal source, such as a driver, and a load. The paths may have different lengths, thus causing delay mismatches. An exemplary circuit of the type described herein may comprise delay elements and at least one feedback circuit designed to compensate for such delay mismatches. The circuit may operate in different phases, such as a compensation phase and a driving phase. In the compensation phase, rings oscillators including delay elements and the at least one feedback circuit may be formed. In this phase the delay may be adjusted to compensate for mismatches. In the driving phase, the signal source may be connected to the load.
