Abstract (en)
An integrated circuit based transformer comprising a first layer of electrically conductive material and a second layer of electrically conductive material. The transformer comprises a primary winding having a first and a second portion (713, 711), wherein the first portion (713) of the primary winding is formed in the first layer of electrically conductive material and the second portion (711) of the primary winding is formed in the second layer of electrically conductive material; and a secondary winding having a first and a second portion (712, 714), wherein the first portion (712) of the secondary winding is formed in the second layer of electrically conductive material, and the second portion (714) of the secondary winding is formed in the first layer of electrically conductive material.
