Abstract
A high gain stacked cascade amplifier includes a first amplifying element, a second amplifying element, a current mirror bias element, and a dynamic bias adjustment element. The first and second amplifying elements are coupled in series to form the high gain stacked cascade amplifier configuration. The current mirror bias element provides a bias to the first and second amplifying elements. The dynamic bias adjustment element is coupled to the second amplifying element. The dynamic bias adjustment element is configured to increase a gain compression point of a composite filter, formed by the first and second amplifying elements, in response to a determination that an input signal causes gain compression in the first amplifying element.
