Appeal No. 96-3902
Application 08/442,742
signal processing system, such as the handset of a cordless phone. In the mixed signal
processing system, plural stable power voltages are required for the reliable and efficient
operation of the handset to extend the operational duration of the rechargeable battery
power source and for proper, efficient operation of the CMOS circuitry. The system uses a
stable, precise reference voltage to maintain the system voltages for the digital and analog
subsystems in the system as the battery power source varies in voltage over time. The
system uses plural voltage regulators to maintain the system voltages.
The prior art references of record relied upon by the Examiner in rejecting the
appealed claims are:
