Abstract
Certain aspects of the present disclosure generally relate to using cross-coupled transistors for source degeneration of an amplification stage. For example, the amplification stage generally includes a differential amplifier comprising transistors, cross-coupled transistors coupled to the differential amplifier, and an impedance coupled between drains of the cross-coupled transistors. In certain aspects, the differential amplifier comprises a push-pull amplifier, and the transistors of the push-pull amplifier comprise cascode-connected transistors.
