  • Switching circuit and envelope signal amplifier
    Patent number: 8878604
    Abstract: A switching circuit according to one embodiment has: N switching elements; a connection circuit including N?1 first inductance elements that are connected in series; a second inductance element; and N third inductance elements. Control terminals of the N switching elements are connected to ends of the connection circuit and connection contacts, respectively. One end of the second inductance element is connected to a power supply. The N third inductance elements electrically connects one ends of the N switching elements and the other end of the second inductance element with each other, respectively.
