Appeal No. 2001-0740
Application 09/054,415
BACKGROUND
The disclosed invention relates to an amplifier which
utilizes switching of a variable power source to provide
different levels of power to the amplifier during different
portions of an operational cycle, such as providing high power
during an expected slewing phase when an amplifier's output
changes at its maximum rate and a reduced power during less
demanding phases, such as during settling or holding. By
increasing maximum output current during the period when slew is
likely to occur, the current in the amplifier during settling can
be decreased, which results in a net power savings (spec. at 7).
Claim 1 is reproduced below.
1. An amplifier circuit comprising a power control
circuit configured to provide relatively high power to an
active element during at least one portion of an amplifier's
operational cycle and to provide relatively low power
otherwise.
The examiner relies on the following references:
Mizuide 4,806,791 February 21, 1989
Wang et al. (Wang) 5,691,720 November 25, 1997
Claims 15 and 16 stand rejected under 35 U.S.C. § 112, first
paragraph, as based on a lack of enabling disclosure.
Claims 1-8, 11, 15, 17, and 18 stand rejected under
35 U.S.C. § 112, second paragraph, as being indefinite for
failing to particularly point out and distinctly claim the
subject matter which appellants regard as their invention.
