ABSTRACT:
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.
