Abstract
A voltage generator circuitry includes first to third bipolar transistors having commonly-connected base electrodes, first and second current mirror circuitries, first and second differential amplifiers; a first resistor; and a current-voltage conversion circuitry. The first current mirror circuitry supplies currents to the first to third bipolar transistors and to the current-voltage conversion circuitry. The second current mirror circuitry supplies currents to the first to third bipolar transistors, and s to the current-voltage conversion circuitry. The first and second differential amplifiers control the first and second current mirror. The current-voltage conversion circuitry converts a sum current of the first and second currents into an output voltage.
