ABSTRACT:
Disclosed is an integrated circuit comprising a balanced set of inputs and a phase splitting circuit. The phase splitting circuit has a first input terminal that is coupled to the balanced set of inputs and a second input terminal that is coupled to the balanced set of inputs. The phase splitting circuit further comprises a balanced phase shifting network, a first set of output terminals, and a second set of output terminals. The balanced phase shifting network is coupled to the first: input terminal and the second input terminal. The first set of output terminals provides a voltage representative of a first voltage across a resistive portion of the balanced phase shifting network in response to an input voltage at the balanced set of inputs. The second set of output terminals provides a voltage representative of a second voltage across a reactive portion of the balanced phase shifting network in response to the input voltage at the balanced set of inputs.
