Abstract
An embodiment of the present invention is directed to a current feedback amplifier. The amplifier is coupleable with a first supply rail and a second supply rail. The current feedback amplifier includes an input stage configurable to provide a first input and a second input for the current feedback amplifier, wherein the first and second inputs are operable to receive input voltages within 800 mV of the first supply rail or the second supply rail. The amplifier further includes a first current mirror coupled with the input stage, a second current mirror coupled with the input stage, and an output stage coupled with the first and second current mirrors. The output stage is operable to provide an output for the current feedback amplifier.
