Abstract: A converter of a differential input signal into a single-ended output signal, has a differential pair of identical transistors first and second driven by the differential input signal, and a circuit for filtering DC components, connected between the current terminal of the second transistor not in common with the first transistor of the differential pair and an output node of the converter on which the single-ended output signal is generated.
It generates a single-ended signal without employing a transformer, in lieu thereof the converter includes:

a current generator biasing the differential pair by means of two output transistors, third and fourth, in current mirror configuration, connected in series with the transistors first and second, respectively;
degeneration resistors of the transistors of the current mirror, dimensioned such that the gains of the converter for each of the two input nodes of the differential signal are equal and of opposite sign.

Abstract: The wireless galvanic isolator device is formed by a transmitter circuit (31), a receiver circuit (32), and a wireless coupling structure, arranged between the transmitter circuit and the receiver circuit (32). The wireless coupling structure is formed by a pair of antennas (33a, 33b) each arranged on an own die (25, 26) and integrated together with the respective transmitter and receiver circuit (31, 32). The two dice can be arranged adjacent to each other in a planar configuration or arranged on top of each other and bonded together.
