Appeal No. 2006-1816 Application No. 10/386,146 multiplexor including a plurality of transmission gates, each transmission gate including a first pass transistor corresponding to a respective signal path of one of the differential inputs, wherein the multiplexor further includes at least one first blocking element coupled between a back-gate node of each first pass transistor and a supply voltage to block a first leakage current path from the back-gate node to the supply voltage, and at least second blocking element coupled between a gate node of each first pass transistor and the respective signal path corresponding thereto to block a second leakage current path from the respective signal path to the first pass transistor. The Examiner relies on the following prior art references: Ko 5,955,912 Sep. 21, 1999 Graves et al. (Graves) 6,100,719 Aug. 8, 2000 Claims 1, 2, 5-8, 10, 12-15 and 171 stand rejected under the second paragraph of 35 U.S.C. § 112 as being indefinite. Claims 1, 2, 5-8, 10, 12-15 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Ko and Graves. 1The Examiner’s indication of allowability of claim 17 appears to have been intended in absence of rejection based on prior art. 3Page: Previous 1 2 3 4 5 6 7 8 9 10 11 NextLast modified: November 3, 2007
