Patent ID: 8493148

Claim:
A differential amplifier, comprising: a first pair of output transistors, wherein first outputs of the first pair of output transistors provide a differential output of the differential amplifier; and a second pair of output transistors, wherein first outputs of the second pair of output transistors are coupled to respective first outputs of the first pair of output transistors, wherein second outputs of the second pair of output transistors provide changes in output to approximately match changes in output of second outputs of the first pair of output transistors, wherein inputs of the second pair of output transistors are cross-coupled to the first outputs of the first pair of output transistors, wherein the first pair of output transistors includes first and second output transistors and the second pair of output transistors includes third and fourth output transistors, wherein: the input of the third transistor is a gate coupled to the first output of the second output transistor; and the input of the fourth transistor is a gate coupled to the first output of the first output transistor, wherein: the input of the third transistor is capacitively coupled to the first output of the second output transistor; and the input of the fourth transistor is capacitively coupled to the first output of the first output transistor.
