A differential pair includes a first and second transistors each having a control terminal coupled to a first input voltage, and a third and fourth transistors each having a control terminal coupled to a second input voltage. The first, second, third, and fourth transistors each has a first current handling terminal coupled to a reference voltage. The first and second transistors each has a second current handling terminal coupled to a first current mirror. The third and fourth transistors each has a second current handling terminal coupled to a second current mirror. A resistor is coupled between the second current handling terminals of the second and third transistors. The differential pair is capable of attaining a high slew rate and a possible common mode input voltage of ground while drawing only a small quiescent current.
