Appeal No. 1998-0441
Application 08/713,089
as claimed. Accordingly, Sakurai does not anticipate
claim 17. The rejection of claim 17 is reversed.
We further note that the Examiner has not demonstrated
that the bias circuits B1, B2, and B4 in Figures 5, 9, and
10, respectively, supply a constant voltage signal
regardless of the variation in voltage of the power source
voltage VDD. While it is true that the frequency stability
over a range of power source voltage is improved as shown in
Figure 8, this does not imply that the outputs of
transistors P16 and N16 have a constant voltage over a range
of external voltages.
We still further note that Figure 10 shows only a
single current control transistor for each inverter (e.g.,
N11) and so does not show third and fourth MOS transistors
for maintaining the current of the inverter circuits
constant as recited in claim 17.
35 U.S.C. § 103
Claims 2, 3, 7-9, 11-14, 16, and 17
The Examiner finds (EA7):
Motegi et al and Sakurai are discussed above, and
are enough for this rejection. Dingwall et al
