Appeal No. 1997-0274
Application No. 08/266,912
BACKGROUND
The appellants’ invention relates to a bias pump arrangement including a signal-
transistion-detection circuit. An understanding of the invention can be derived from a
reading of exemplary claim 1, which is reproduced below.
Claim 1. A circuit comprising:
a charge pumping circuit, responsive to a signal having high and low
levels on a lead, for alternately storing charge in a pumping capacitor and
transferring the stored charge from the pumping capacitor to a load;
a terminal for receiving an input signal having negative-going and
positive-going transitions;
a first signal-transition-detection circuit, responsive to the negative-
going input signal transitions on the terminal, for producing and applying to
the lead of the charge pumping circuit a full-cycle signal having high and low
levels for each negative-going input signal transition; and
the first signal-transition-detection circuit, further responsive to the
positive-going input signal transitions on the terminal, for producing and
applying to the lead of the charge pumping circuit a full-cycle signal having
high and low levels for each positive-going input signal transition.

The prior art references of record relied upon by the Examiner in rejecting the
appealed claims are:
3The Examiner has cited U.S. Patent 5,047,659 to Ullrich as evidence, but did not include this
reference in the rejection applied against claims 1-5.
