Abstract
A system includes a first amplifier stage and a second amplifier stage. The first amplifier stage is configured to amplify an input signal and generate first output signals. The first amplifier stage includes a common-source differential amplifier. The common-source differential amplifier includes a plurality of metal-oxide semiconductor field-effect transistors (MOSFETs) having source terminals connected to a common potential. The second amplifier stage includes a first differential amplifier and a second differential amplifier configured to respectively generate first and second differential outputs based on the first output signals. Each of the first and second differential amplifiers includes a plurality of MOSFETs having source terminals connected to the common potential via a respective balun.
