description A solid state relay circuit arrangement (10, 20) for audio signals is described, of the type comprising a first MOSFET (M1) and a second MOSFET (M2) in a back-to-back configuration, configured to receive an input signal ( V s1 ; V 1 , V 2 ) on the source electrode (S1) of the first MOSFET (M1) and to take the output signal (V s2 ; V o1 , V 02 ) on the source electrode (S2) of the second MOSFET (M2), with a driving voltage ( V bias ) being applied to the gate electrodes (G1, G2) of said first MOSFET (M1) and second MOSFET (M2), apt to change, on the basis of its value, the operational state of said first MOSFET (M1) and second MOSFET (M2), According to the invention, each of said first MOSFET (M1) and second MOSFET (M2) comprises a respective bypass capacitor (23, 25) arranged between its source electrode (S1, S2) and its gate electrode (G1, G2), having such a capacitance value (C1) to determine a bypass path for the input signal ( Vs 1 ; V 1 , V 2 ) from the source electrode (D1, D2) to the gate electrode (G1, G2) in the operating frequency range of said input signal ( Vs 1 ; V 1 , V 2 ).
