Abstract: A system on a package (SOP) can include a galvanic isolator. The galvanic isolator can include an input stage configured to transmit an input RF signal in response to receiving an input modulated signal. The galvanic isolator can also include a resonant coupler electrically isolated from the input stage by a dielectric. The resonant coupler can be configured to filter the input RF signal and transmit an output RF signal in response to the input RF signal. The galvanic isolator can further include an output stage electrically isolated from the resonant coupler by the dielectric. The output stage can be configured to provide an output modulated signal in response to receiving the output RF signal.

Abstract: An apparatus is provided. A differential pair of transistors is configured to receive a first differential signal having a first frequency, and a transformer, having a primary side and a secondary side is provided. The primary side of the transformer is coupled to the differential pair of transistors, and the secondary side of the transformer is configured to output a second differential signal having a second frequency, where the second frequency is greater than the first frequency. A first transistor is coupled to the first supply rail, the primary side of the transformer, and the differential pair of transistors, where the first transistor is of a first conduction type. A second transistor is coupled to the second supply rail, the primary side of the transformer, and the differential pair of transistors, where the second transistor is of a second conduction type.
