Abstract:
An apparatus is disclosed that includes a first cross-coupled transistor pair, a second cross-coupled transistor pair, at least one capacitance unit, and an inductive unit. The first cross-coupled transistor pair and second cross-coupled transistor pair are coupled to a pair of first output nodes and a pair of second output nodes, respectively. The at least one capacitance unit is coupled to at least one of the pair of first output nodes and the pair of second output nodes. The inductive unit is coupled to the first cross-coupled transistor pair at the first output nodes and coupled to the second cross-coupled transistor pair at the second output nodes. The inductive unit generates mutual magnetic coupling between one of the first output nodes and one of the second output nodes and between the other of the first output nodes and the other of the second output nodes.
