Abstract
An apparatus includes a first circuit and a second circuit. The first circuit may be configured to generate (i) a variable current and (ii) a constant current. The variable current may be proportional to a temperature of the first circuit. The second circuit may be configured to present a resistance through a plurality of first transistors between two ports in response to both the variable current and the constant current. The resistance may have a predefined dependence on the temperature.
