Appeal No. 1998-1444 Page 3
Application No. 08/543,933
Claim 11, which is representative for our purposes, is
reproduced from the brief as follows:
11. A reference voltage generating circuit for
generating a reference voltage that changes linearly
with temperature, the reference voltage generating
circuit comprising:
a constant-voltage power supply for outputting a
constant voltage and having first and second output
terminals;
a voltage divider circuit connected between the
first and second output terminals; and
a constant-current source connected to a voltage
divider junction of said voltage divider circuit for
linearly changing with temperature current flowing
into or out of said voltage divider junction, a
reference voltage linearly changing with temperature
being output from said voltage divider junction.
The references relied on in rejecting the claims follow:
Yum et al. (Yum) 5,327,028 July 5,
1994
Buck et al. (Buck) 4,990,846 Feb. 5, 1991.
Claims 11-13 stand rejected under 35 U.S.C. § 103 as obvious
over Yum in view of Buck. Rather than repeat the arguments of
the appellant or examiner in toto, we refer the reader to the
brief and answer for the respective details thereof.
