Resistor Ladder Voltage Generator for Stable Internal References

The voltage generator is modified to generate its own reference voltages using an internal voltage generation circuit. The circuit includes a reference voltage generation unit that creates stable reference voltages from the power supply voltage itself, eliminating the need for external reference voltage inputs. This self-service approach resolves the contradiction by making the device independent while maintaining reliable reference voltage generation.

The reference voltage generation function is extracted from the external environment and integrated into the voltage generator itself. By incorporating an internal reference voltage generation circuit, the patent removes the dependency on external reference voltage sources while maintaining the essential function of providing stable reference voltages to the analog/digital converter.

The voltage generation circuit incorporates feedback mechanisms that monitor power supply voltage variations and automatically adjust the reference voltage generation to compensate for these changes. This feedback control ensures that reference voltages remain stable even when power supply voltage fluctuates, resolving the contradiction between stability and power supply dependence.

The circuit dynamically adjusts its operating parameters based on power supply voltage conditions. By changing the generation parameters of the reference voltages in response to power supply variations, the circuit maintains stable output reference voltages while adapting to different power supply conditions, thus eliminating the harmful dependence on power supply stability.
