appellant's specification. However, we understand it to mean the
primary current path through the device. That is consistent with
the specification's description of the connection between current
mirror transistors 22 and 24 and differential mode transistors 22
and 24. On page 4 of the appellant's specification, it is
described that the conductance paths of current mirror
transistors 26 and 28 are "series-connected" with the conductance
paths of transistors 22 and 24, respectively. As is shown in the
appellant's sole Figure, the drain of transistor 22 is coupled to
the drain of transistor 26, and the drain of transistor 24 is
coupled to the drain of transistor 28. In the case of bipolar
transistors, it means "conductance path" refers to the current
path between the emitter and the collector. That is also
consistent with the examiner's finding (Paper No. 9, page 3) with
respect to Sakai that the conductance paths of transistors Q6 and
Q9 are individually coupled to the conductance paths of
transistors Q3 and Q4.
In Sakai, transistor Q5's collector is coupled to neither
the collector nor emitter of either transistor Q6 or Q9. Also,
transistor Q5's emitter is coupled to neither the collector nor
emitter of either transistor Q6 or Q9. Moreover, the base of
transistor Q5 is not in direct connection with any electrode of
