| Zusammenfassung: | A wideband differential amplifier includes a first differential stage connected to a Miller stage allowing an open-loop gain increase. The Miller stage includes a current source and a resistive-capacitive network causing a feedback into the current source. The feedback includes a portion of a Miller stage output signal having a high frequency range to move a bias point of the current source within the high frequency range. Thus, a gain of the Miller stage significantly increases towards the bias point. |
