  • Patent number: 9791879
    Abstract: A voltage reference circuit is provided that includes a first circuit, a second circuit and a third circuit. The first circuit has a first MOS transistor pair and the second circuit has a second MOS transistor pair. The first circuit is configured to provide a first voltage component that changes at a first rate having a first slope as a temperature to which the voltage reference circuit is subjected changes. The second circuit is configured to provide a second voltage component that changes at a second rate having a second slope as the temperature changes. The third circuit is configured to use the first voltage component and the second voltage component to generate the reference voltage component that changes at a fifth rate having a fifth slope as the temperature changes. The fifth slope is substantially equal to zero to promote insensitivity of the reference voltage component to temperature changes.

    Abstract: In a method, conductive lines used in a circuit are formed. Signal traces of a plurality of signal traces are grouped to a first group of first signal traces or a second group of second signal traces. A first mask is used to form a first conductive line for a first signal trace of the first group. A second mask is used to form a second conductive line for a second signal trace of the second group. The first traces each have a first width. The second traces each have a second width different from the first width. The grouping is based on at least one of following conditions: a current flowing through a signal trace of the signal traces of the plurality of signal traces, a length of the signal trace, a resistivity of the signal trace, or a resistivity-capacitive constant of the signal trace.
