  • HIGH SPEED AMPLIFIER
    Publication number: 20130063210
    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.

  • HIGH SPEED AMPLIFIER
    Publication number: 20130015918
    Abstract: For high speed amplifiers, the parasitic capacitances between a differential input pairs and a cascoded bias network can introduce a pole that can affect performance. Here, a feedforward network has been provided that compensates for this pole by introducing a zero that effectively cancels the pole, moving the next parasitic without any additional power. This is generally accomplished by using a pair of feedforward capacitors coupled across the transistors of the cascoded bias network, which reduced power consumption.
