The design of a current-feedback (CF) amplifier for high end power audio applications, up to 200 W RMS, is presented. Measured results prove that the proposed scheme achieves optimal signal-to-noise ratios and total harmonic distortion levels on the entire audible frequency range. Thanks to the CF topology the amplifier also features high bandwidth and high slew-rate.
