Abstract
Amplifier devices includes a first amplifier connected to receive an input voltage. The first amplifier outputs an internal voltage. These structures also include a second amplifier having an input node connected to receive the internal voltage and an output node outputting an output voltage. A resistive feedback loop is connected to the input node and the output node of the second amplifier. A first cross-coupled bandwidth boosting stage is connected to the input node of the second amplifier and a second cross-coupled bandwidth boosting stage connected to the output node of the second amplifier. The cross-coupled bandwidth boosting stages form a distributed differential positive feedback structure.
