Claim Text:
1. A differential amplifier that, when connected to a positive or negative supply voltage and to a ground voltage, provides a differential pair of outputs signals at a differential output that are an amplification of a differential pair of input signals at a differential input, comprising: a differential input stage that receives the differential pair of input signals from the differential input and that includes a first transistor associated with one of the input signals and a second transistor associated with the other input signal; and a differential output stage that generates the differential pair of output signals at the differential output and that includes a third transistor associated with one of the output signals and a fourth transistor associated with the other output signal, wherein the first, second, third, and fourth transistors are all P type or all N type, and wherein the differential pair of output signals has a common mode that is:
