摘要： An active balun uses two inverters to produce a differential output from a single-ended input. A current source supplies current to both inverters and a current sink sinks current from both inverters. The inverters include bias resistors coupled between their inputs and outputs. A coupling capacitor couples the output of the first inverter to the input of the first inverter. Values of the bias resistors and the coupling capacitor may selected to assure stability of the active balun. The values may be programmable, for example, based on a desired operating frequency. The current source may be biased by a common-mode feedback circuit based on the common-mode voltage of the differential output.

摘要： A phase shifting stage is disclosed. The phase shifting stage includes first and second transistors. Second terminals of the first transistor and the second transistor are coupled to a first current tail node. A third transistor and a fourth transistor have second terminals that are coupled to a second current tail node. Also included is a first transformer having a primary winding with first and second inputs and a secondary winding. The first input is coupled to the first terminals of the first and third transistors, and the second input is coupled to the first terminals of the second and the fourth transistors. A common input stage having high power gain and phase commutating cascode stages in asymmetrical transformer output demultiplexing (ATODEM) branches is also provided. The common input stage limits the noise generated at an input stage by substantially canceling out the noise at an output transformer of the ATODEM.
