Application No. 08/800,972
which case neither of the body bias transistors 84 and 86 are
turned on.
In reaching this conclusion, we are further persuaded by the
Examiner’s presentation of evidence in the form of the Moyer
reference which, in analyzing the operation of the Fuller circuit,
discloses that both of Fuller’s body bias transistors are “... off
simultaneously whenever the voltages at the drain and source of
transistor 10 are very nearly the same.” (Moyer, column 1, lines
59-63). As pointed out by the Examiner (Answer, page 6), although
the language “very nearly the same” implies a very small voltage
range, it nonetheless clearly indicates a non-zero interval or
“deadband” during which both body bias transistors in Fuller are
simultaneously off.
Turning to a consideration of the Examiner’s 35 U.S.C.
§ 103(a) rejection of claims 18, 20, 24, and 31, we note that,
while we found Appellants’ arguments to be unpersuasive with
respect to claims 16, 17, 19, and 25-29 discussed supra, we reach
the opposite conclusion with respect to claims 18, 20, 24, and 31.
