the claim essentially requires that one of the internal power
supply voltages is in turn a reference voltage for producing the
other internal power supply voltage as argued by appellant in the
brief and reply brief. The overall circuit shown in figure
5 does not meet this limitation since a common reference voltage
VREF feeds in parallel both the top and bottom subcircuit
elements in figure 5.
