Appeal No. 2004-0593 Application No. 09/606,688 No further discussion of what is “matched” or “substantially matched” appears in the specification, to our knowledge. Indeed, this passage from the specification appears to undercut the appellant’s argument that IC device transistors are not ordinarily “matched” within the broadest reasonable interpretation of the word. Similar to the position taken by the examiner, it would appear that the appellant’s own specification indicates that transistors on the same integrated circuit are generally matched (as opposed to discrete components), unless otherwise stated. Rempfer’s transistors appear to be manufactured on the same IC. Consequently, we agree with the examiner that Rempfer’s transistors are properly found to be “matched” or “substantially matched.” The appellant has provided no convincing evidence to the contrary. The appellant next urges that claims 1, 7, 13, and 25 recite a buffer/voltage-mirror arrangement adapted to cause an output voltage on said output to mirror an input voltage on said input by a predetermined factor. Rempfer, it is said, discloses an amplifier configuration wherein the W/L ratio of the first and second transistors is N times larger than the W/L ratio of the third and fourth transistors.
