Current Feedback Amplifier

To design high speed and low voltage analog circuits nowadays designers have started using current mode approach. It means that the individual circuit elements should interact by means of currents not voltages. Due to this change in signal definition analog signal processing circuits must also be changed from voltage to current mode. In this regard there is a need of several ranges of current amplifier architectures with high speed and low voltage for various applications. The architecture discussed in this book is based on current conveyor. The current conveyor is basic building block used to convey current.
