Patent attributes
A circuit is provided that includes a first transistor having a first terminal, a second terminal and a third terminal, and a second transistor comprising a first terminal, a second terminal and a third terminal. The first terminal of the first transistor comprises an input terminal of the circuit, the second terminal of the first transistor is coupled to a power supply bus, and the first transistor conducts a first current. The first terminal of the first transistor comprises an output terminal of the circuit, the second terminal of the second transistor is coupled to the power supply bus, and the third terminal of the second transistor is coupled to the third terminal of the first transistor. The second transistor conducts a second current proportional to the first current substantially independent of distance between the first transistor and the second transistor.
