Abstract:
1. A coupling circuit comprising: a solid-state relay having an input terminal and an output terminal; a first inductor having a first terminal configured to couple to a source providing an input signal, and a second terminal coupled to the input terminal of the solid-state relay; a second inductor having a first terminal coupled to the output terminal of the solid-state relay, and a second terminal configured to couple to an input of a device; and a capacitor coupled between the input terminal and the output terminal of the solid-state relay; wherein the solid-state relay is configured to couple the input signal to the device through the capacitor when operated in AC coupled mode, and wherein the solid-state relay is configured to couple the input signal to the device bypassing the capacitor when operated in DC coupled mode.
