Abstract
A circuit for calibrating a resistance between a first circuit node and a second circuit node is disclosed. The circuit comprises a reference resistor connected between first and second reference nodes; a first transistor having a first current-handling terminal connected to the first reference node, a second current-handling terminal, and a first control terminal; and a second transistor having a third current-handling terminal connected to the first circuit node, a fourth current-handling terminal connected to the second circuit node, and a second control terminal connected to the first control terminal.
