Dynamically controlled amplifier

摘要

A dynamically controlled amplifier circuit includes a first difference circuit having a first primary differential amplifier and a first crossover differential amplifier running in parallel with the first primary differential amplifier. A second difference circuit has a second primary differential amplifier and a second crossover differential amplifier running in parallel with the second primary differential amplifier. An input terminal is coupled to control electrodes of the first primary differential amplifier and to control electrodes of the second primary differential amplifier. An output terminal of the first primary differential amplifier is coupled to control electrodes of the second crossover differential amplifier, and an output terminal of the second primary differential amplifier is coupled to control electrodes of the first crossover differential amplifier.
