Abstract

See full text

Certain aspects of the present disclosure provide methods and apparatus for amplifying an input signal. One example apparatus is a differential amplifier that includes a positive input node, a negative input node, a positive output node, a negative output node, a positive input transistor having a gate coupled to the positive input node and having a drain coupled to the negative output node, a negative input transistor having a gate coupled to the negative input node and having a drain coupled to the positive output node, a first common-gate amplifier having an output coupled to the negative output node, a second common-gate amplifier having an output coupled to the positive output node, a first capacitive element coupled between the negative input node and an input of the first common-gate amplifier, and a second capacitive element coupled between the positive input node and an input of the second common-gate amplifier.
