Appeal No. 96-3040
Application 08/135,650
as being directed to a nonelected invention. Claims 9-29 and 32-35 have been indicated
by the examiner as containing allowable subject matter. Amendments after final rejection
were filed on November 6, 1995 and December 11, 1995. Both of these amendments
were entered by the examiner.
The disclosed invention pertains to a voltage supply circuit driven by a power supply
voltage for supplying power to internal circuits of an integrated circuit device. A particular
feature of the invention is the capability of supplying a stable voltage to the internal circuits
regardless of temperature variations occurring within the integrated circuit.
Representative claim 1 is reproduced as follows:
1. A voltage supply circuit driven by a power supply voltage for supplying an output
voltage, comprising:
reference voltage generation means driven by said power supply voltage for
generating a reference voltage;
driver means receiving said power supply voltage and supplying said output
voltage;
dividing means including first and second resistor means for dividing the output
voltage supplied by said driver means and supplying a divided output voltage, said first
and second resistor means having resistance values of different temperature coefficients;
and
comparison means for comparing said divided output voltage supplied by said
dividing means and said reference voltage generated by said reference voltage
generation means and controlling said driver means based on the difference between said
divided output voltage and said reference voltage.
