EnglishA galvanic isolation circuit (GI) includes a differential transformer (20) having primary (21) and secondary (22) windings for transmission of signals over a carrier (DT) between the primary (21) and the secondary (22) windings of the transformer. The primary (21) and secondary (22) windings have a galvanic isolation oxide layer (23) therebetween and include center taps (21a, 22a) providing low-impedance paths for dc and low frequency components of common-mode currents through the differential transformer (20). A pass-band stage (24) coupled to the secondary winding (22) of the transformer (20) is configured for permitting propagation of signals over said carrier through the pass-band amplifier stage (24) while providing rejection of common-mode noise.
