a planar transformer arrangement and method provide isolation between an input signal and an output signal . the planar transformer arrangement includes a planar medium having a first layer , a second layer , and a dielectric interlayer arranged between the first and second layers ; at least one meandering primary winding arranged on the first layer of the planar medium , a current flow being induced within the primary winding in accordance with the input signal ; at least one meandering secondary winding arranged on the second layer of the planar medium , the primary and secondary windings forming a planar transformer , whereby a voltage is induced across the secondary winding in accordance with the current flow within the primary winding ; and a mode elimination arrangement configured to produce a compensated voltage by compensating for a common mode interference on the voltage induced across the secondary winding , the mode elimination arrangement being further configured to generate the output signal in accordance with the compensated voltage ; wherein the dielectric interlayer of the planar medium provides a voltage isolation between the primary and secondary windings .
