| 1. A device, comprising:
a phase differential module comprising a first input to receive a first signal having a first phase, a second input to receive
a reference signal having a second phase, and an output to provide a phase difference signal based on a difference between
the first phase and the second phase; and
a phase detection module comprising
a first multi-gate FinFET comprising a first gate electrode coupled to the output of the phase differential module, a second
gate electrode coupled to receive a first phase threshold signal, a first current electrode to provide a first phase indicator
signal, and a second current electrode.
