摘要: Amplifier systems and methods are provided which closely approximate a constant output impedance quiescent signal during forward reverse modes of operation. The can be realized with small, inexpensive components that compatible integrated-circuit fabrication processes. A system embodiment includes amplifier, feedback path is coupled across at least part the amplifier to reduce its impedance, drive portion generator controls operational timing amplifier. Another an error-current canceler cancels error currents substantially equal opposite correction currents.
