DIFFERENTIAL OPERATIONAL AMPLIFIER WITH CURRENT RE-USING FEEDFORWARD FREQUENCY COMPENSATION

摘要

The present invention relates to a differential amplifier using a feed-forward frequency compensation scheme for reusing the current, in the present invention Article according differential amplifier using the feed-forward frequency compensation scheme for reusing current amplifies the input signal and outputting the first amplifier stage, the second amplifier stage that amplifies the output signal of the first amplifier stage, the first amplification stage and the second amplification stage is electrically connected to at least one of a, including, but for the first stage feed-forward amplifier stage or to clear the at least one pole (pole) of the second amplifier stage, the current flowing through the feed-forward stage is the first stage and can be characterized in that the previously used current at any one stage of the second stage. A differential amplifier using a feed-forward frequency compensation scheme for reusing current according to the present invention can have a wide band characteristic with minimal power consumption, there is an effect that can be used in electronic applications which require low power consumption and high performance.
