Abstract
A time to digital converter (TDC) may include a sampling stage configured to sample an input signal based upon a plurality of timing signals having different respective phases, and provide a respective output for each of the different timing signals. A first synchronization stage may be configured to receive the outputs from the sampling stage, synchronize a first subset of the outputs to a first one of the plurality of timing signals, and synchronize a second subset of the outputs to a second one of the plurality of timing signals. A second synchronization stage may be configured to receive the synchronized outputs from the first synchronization stage, and synchronize all of the synchronized outputs from the first synchronization stage to the first one of the plurality of timing signals.
