  • Solid state relay circuit arrangement for audio signals and switching system
    Patent number: 9544686
    Abstract: A solid state relay circuit arrangement for audio signals is described, of the type comprising a first MOSFET and a second MOSFET in a back-to-back configuration, adapted to receive an input signal on the source electrode of the first MOSFET and to take the output signal on the source electrode of the second MOSFET, with a driving voltage being applied to the gate electrodes of said first MOSFET and second MOSFET, apt to change, on the basis of its value, the operational state of said first MOSFET and second MOSFET, According to the invention, each of said first MOSFET and second MOSFET includes a respective bypass capacitor arranged between its source electrode and its gate electrode, having such a capacitance value to determine a bypass path for the input signal from the source electrode to the gate electrode in the operating frequency range of said input signal.
