A device and method for phase detection are disclosed. The device includes
a phase differential module that provides a phase difference signal based
on the phase difference between a data signal and a reference signal. The
phase difference signal is provided to a first gate of a multi-gate
fin-type field effect transistor (multi-gate FinFET) of the device. A
second gate of the multi-gate FinFET transistor receives a bias signal
that provides a phase detection threshold. A phase adjustment signal is
provided at one or both of the FinFET current electrodes based on the
phase difference signal and the bias signal.
