Abstract:
Certain aspects of the present disclosure provide methods and apparatus for processing an input signal. One example apparatus is a circuit that generally includes an amplifier, comprising a first transistor and a second transistor connected in cascode with the first transistor; a buffer coupled to an output of the amplifier and configured to provide feedback to the amplifier; and a current source coupled to the second transistor and incorporated into a loop of the feedback to the amplifier.
