Spintronic phase comparator permitting direct phase probing and mapping of electromagnetic signals

摘要

An apparatus, system, and method for phase detection of electromagnetic signals are presented. The apparatus may include a magnetic element, one or more first signal contacts coupled to the magnetic element for receiving a first signal, and one or more output contacts coupled to the magnetic element for providing a variable level voltage generated by the magnetic element, the level of the voltage being responsive to a phase difference between the first signal and a second signal. In a further embodiment, the apparatus may include a substrate for mechanically supporting the magnetic element. Additionally, the apparatus may include a conductor mechanically supported by substrate, the conductor configured to receive the second signal.
