  • Apparatus and method for feed-forwarding in a current-feedback amplifier
    Patent number: 8159304
    Abstract: A current-feedback amplifier with at least one feed-forward capacitor at the input stage of the current-feedback amplifier is provided. In one embodiment, the current-feedback amplifier and feed-forward capacitor(s) are arranged as follows. The input stage includes two translinear loops, where each translinear loop includes a translinear element that is connected to the non-inverting input of the current-feedback amplifier. One feed-forward capacitor is in parallel with each translinear element that is connected to the non-inverting input of the current-feedback amplifier. In other embodiments, the feed forward capacitor(s) are arranged in a different manner.
