  • Method of monitoring electrical loads, corresponding circuit, amplifier and audio system
    Patent number: 11183981
    Abstract: A method of monitoring electrical loads is disclosed. In an embodiment the method includes generating a first voltage signal and a second voltage signal, the second voltage signal in quadrature to the first voltage signal, injecting one of the first voltage signal or the second voltage signal into a signal propagation path towards an electrical load, sensing a current signal flowing through the electrical load as a result of the one of the first voltage signal or the second voltage signal injected into the signal propagation path and processing the first voltage signal, the second voltage signal and the sensed current signal.

  • Electronic circuit for driving a switching amplifier
    Patent number: 8659351
    Abstract: An electronic circuit is disclosed for driving a switching amplifier. The electronic circuit is configured for generating, when operating in a switch-on mode, a driving signal for driving the switching amplifier. The driving signal carries a plurality of pulses having: an pulse width increasing between contiguous pulses of the plurality of pulses according to a step value having modulus equal to two and odd values; a polarity alternating between the contiguous pulses.
