Claims9
An apparatus comprising:
- a first current mirror arrangement coupled to a first input signal arrangement, the first input signal arrangement comprising a first input current source and a first impedance, the first impedance being at least one physical circuit element;
- and
- a second current mirror arrangement coupled to a second input signal arrangement, the second input signal arrangement comprising a second input current source and a second impedance, the second impedance being at least one physical circuit element, and wherein the second current mirror arrangement is coupled to the first current mirror arrangement,
- wherein the second current mirror arrangement is coupled to the first current mirror arrangement via a reference current source.
