  • Unified bandgap voltage curvature correction circuit
    Patent number: 9128503
    Abstract: A unified bandgap voltage waveform compensation amplifier is arranged having shared input transistor pairs, a shared load resistor, and shared current sources. For example, a first amplifier structure is arranged to produce a negative-going bias correction signal when a bandgap voltage reference increases as operating temperatures rise and a second amplifier structure is arranged to produce a positive-going bias correction signal when the bandgap voltage reference increases as operating temperatures rise. The unified amplifier is arranged to combine the positive-and negative-going signals to generate a combined compensation current that is used to compensate for temperature instability of the bandage voltage reference.
