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.
