Abstract
For high speed amplifiers, the parasitic capacitances from the differential input pair introduce a zero that can affect performance. Here, a neutralization network has been provided that compensates for this zero by shifting its position. This is generally accomplished by using a pair of capacitors that are cross-coupled across the differential input pair of the amplifier.
