  • Stable floating gate voltage reference using interconnected current-to-voltage and voltage-to-current converters
    Patent number: 6768371
    Abstract: A programmable voltage reference circuit that includes a current-to-voltage converter circuit, a voltage-to-current converter circuit, and a floating gate. The current-to-voltage converter circuit has two current input terminals and a voltage output terminal. The voltage-to-current converter circuit has two voltage input terminals and two current output terminals. The two current output terminals are each coupled to a corresponding current input terminal of the current-to-voltage converter circuit. A floating gate device has one terminal coupled to a fixed voltage supply, and one terminal coupled to an input terminal of the voltage-to-current converter. The other input terminal of the voltage-to-current converter is coupled to the voltage reference output terminal of the programmable voltage reference circuit. Also, the voltage output terminal of the current-to-voltage converter circuit is coupled to the negative voltage input terminal of the voltage-to-current input circuit.
