摘要:
A nested feed forward distortion reduction system, which reduces the distortion from a main amplifier (62) on a main signal path, uses a nested feed forward arrangement (82) for the correction amplifier (86) to reduce the distortion produced from the correction amplifier. In reducing the distortion from the correction amplifier(s) and using progressively higher quality correction amplifier(s), the nested feed forward arrangement produces an improved, more stable representation of the distortion from the main amplifier, thereby alleviating the need for variable gain and/or phase control in producing amplified signal with reduced distortion.
