Abstract
Compensation for the effect of parasitic and stray impedance which is present at the inverting input of known current feedback wideband amplifiers is described. The compensation permits these amplifiers to operate at higher frequencies without degrading the gain flatness of the amplifier and also simplifies the circuitry required to maintain correct biasing.
