Abstract
A very low distortion amplifier using one or more error correction loops based on a balanced error negative feedback scheme intrinsically and easily reiterable. Such loops are applied to a generic amplifier block Ain order to reduce its error in a wide frequency band, without substantially interfering, in the correction process, with the main path of the useful signal V, to amplify, whereby the corrected amplifier preserves the same response, in time and frequency, the same dynamic behavior and the same stability margins in amplitude and phase, of the not corrected amplifier A. This result is obtained by means of a balance and reference block A, capable to decouple the error correction loop from the main path of the useful signal V, in a very wide frequency band.
