Abstract: A circuit with galvanic isolation includes a series of n cascaded transformers including a first transformer and a last transformer in the series. A transmitter is coupled to the primary winding of the first transformer in the series of cascaded transformers, the transmitter being configured for supplying to the primary winding a transmission signal as a function of an input signal. A receiver is coupled to the secondary winding of the last transformer of the series of cascaded transformers and is configured for receiving at the secondary winding a reception signal transmitted over the series of cascaded transformers. A predistortion module is configured for applying to the transmission signal a predistortion including an (n−1)-fold integration, where n is the number of cascaded transformers, of a transmission signal that would be supplied to the input of a sole transformer present in a single-transformer solution.
