Claim Text:
1. A Class-G amplifier, comprising: a first and second driving transistor configured to receive an input voltage; a first supplying terminal connected to the first driving transistor to supply a first supplying voltage; a second supplying terminal connected to the second driving transistor to supply a second supplying voltage having an absolute value higher than said first voltage; a first power transistor connected to the first driving transistor to form a first Sziklai transistor pair with complementary feedback and being structured to be activated by a first input voltage having an absolute value lower than the first supplying voltage; a second power transistor connected to the second driving transistor to form a second Sziklai transistor pair with complementary feedback and being structured to be activated by an input signal comprised between the first supplying voltage and the second supplying voltage.
