Appeal No. 2003-0258
Application 09/684,138
The examiner does not provide any evidence in support of this
argument, and there is evidence to the contrary. Rail-to-rail
CMOS buffer amplifiers having a class AB output stage are
disclosed in: 1) “BUF04701 - 4-Channel, Rail-to-Rail, CMOS Buffer
Amplifier”, Texas Instruments Product Brochure, Sep. 2001, at 9;
2) Satoshi Sakurai and Mohammed Ismail, “Robust Design of Rail-
to-Rail CMOS Operational Amplifiers for a Low Power Supply
Voltage”, 31 IEEE J. Solid-State Circuits 146-56 (Feb. 1996);
3) Yajun Ha et al., “Low-Voltage High Driving Capability CMOS
Buffer Used in MEMS Interface Circuits” (undated), at
http://www.ee.nus.edu.sg/stfpage/elelimf/publication/W1F5.pdf,
and Patt Boonyaporn and Varkorn Kasmsuwan, “A High Performance
Class AB CMOS Rail to Rail Voltage Follower”, (undated), at
http://www.ap-asic.org/2002/proceedings/3B/3B-6.PDF. An error
amplifier having a MOS input stage and a class AB output stage is
disclosed in Claudio Adragna, “AN1261 Application Note - Getting
Familiar with the L6590 Family High-Voltage Fully Integrated
Power Supply”, Sep. 2000, at 9, at
http://epu.ref.nstu.ru/DISKOTEKA/Platan/stm/pdf/7309.pdf.1 Thus,
the examiner’s argument that rail-to-rail buffer amplifiers and
