Appeal No. 2001-0740
Application 09/054,415
Appellants argue that Mizuide does not show "during an
operational phase when slew is expected, increasing current
available to the amplifier irrespective of actual signal level
applied to the amplifier" as recited in claim 15 (Br12).
The examiner responds that current is increased to
amplifier 1, 3, 7, 9 when slewing (a transition) occurs,
referring to column 7, lines 36-37 (EA15).
Mizuide is tied to the actual voltages V 1 and V2, which can
occur at any time. Mizuide is not clocked. Thus, there is no
time "when slew is expected" and no teaching of increasing
current during this time. Further, if "slew" is taken to be a
change in voltage level, then slew occurs when voltages V 1 or V2
change, but a change in voltages may result in decreasing current
available to transistors 1 and 3, not just an increase. The
rejection of claim 15 is reversed.
Claim 16
Appellants argue that Mizuide does not show "decreasing
current available to the amplifier during an operational phase
when little activity is expected" as recited in claim 16 (Br12).
The examiner responds that current available to
amplifier 1, 3, 7, 9 is decreased when little activity occurs and
61 is turned off, referring to column 7, lines 43-44 (EA15).
