METHODS AND APPARATUS FOR FACILITATING NEGATIVE FEEDBACK, PROVIDING LOOP STABILITY, AND IMPROVING AMPLIFIER EFFICIENCY

摘要

An amplifier is described having an amplification stage in a first feedback loop. The amplification stage is operable to open the first feedback loop during operation of the amplifier. The amplifier further comprises a feed forward path bypassing the amplification stage. The feed forward path is operable to provide a second feedback loop when the first feedback loop is open.
