Abstract
An amplifying circuit comprises a differential amplifier receiving input signals and having first and second output connections to which the input and output connections of a current amplifier respectively connect. A transistor receives signals at its gate from the second output connection of the differential amplifier and has a capacitor connected between its input and output electrodes. A feed-forward circuit, responsive to signals at the first output connection of the differential amplifier, develops a feed-forward signal which is applied to the output electrode of the transistor and poled so as to reinforce the signals thereat. The feed-forward signals tend to cancel signals conducted through the capacitor at high frequencies where the transistor exhibits reduced gain.
