Patent ID: 8451062

Claim:
A method of amplifying a differential voltage signal, the method comprising: receiving, by each of a plurality of amplification units, a differential voltage signal comprising a first component and a second component; determining, via each of the plurality of amplification units, a difference between the first component and the second component of the differential voltage signal; amplifying, via each of the plurality of amplification units, the difference between the first component and the second component of the differential voltage signal to generate a plurality of amplified difference signals that each correspond to the amplified difference, wherein at least two of the plurality of amplification units comprises a first amplification circuit, a second amplification circuit, and a driver unit, and wherein the driver unit is configured to receive a first output of the first amplification circuit and a second output of the second amplification circuit, and combine the first output and second output as an amplified difference signal; combining the plurality of amplified difference signals to generate a common output signal that corresponds to the amplified difference; and outputting the common output signal.
