Abstract
Exemplary embodiments are directed to systems, devices, and methods for enhancing an amplifier. An amplifier may include a first cascode circuit including a first transistor and a second transistor. The amplifier may include a second cascode circuit coupled to a differential output and including a first pair of transistors including a first transistor and a second transistor and a second pair of transistors including a third transistor and a fourth transistor. Further, the amplifier may include a differential input including a first transistor coupled to each of the first transistor of the first cascode circuit and the first and second transistors of the second cascode circuit, the differential input further including a second transistor coupled to each of the second transistor of the first cascode circuit and the third and fourth transistors of the second cascode circuit.
