    Hello,

    Is there a way to perform AC coupling without the use of a capacitor?

    Thanks in advance!

    Sure. Use a transformer.

    Welcome to AAC!

    The more information you give, the more you get back.

    Thanks!! :)

    Must the number of turns on each side be equal to use a transformer for ac coupling purposes please?

    The ratio need not be 1:1 in every case. One advantage of transformer coupling is the possibility of using different ratios for impedance matching.

    This may be done to obtain optimum gain, where stages with different output and input impedances are coupled together.
