Abstract:
In some embodiments, an apparatus includes a bandgap reference circuit having a first bipolar junction transistor (BJT) that can receive a current from a node having a terminal voltage and can output a base emitter voltage. The apparatus also includes a second bipolar junction transistor (BJT) having a device width greater than a device width of the first BJT. The second BJT can receive a current from a node having a terminal voltage and output a base emitter voltage. In such embodiments, the apparatus also includes a reference generation circuit operatively coupled to the first BJT and the second BJT, where the reference generation circuit can generate a bandgap reference voltage based on the base emitter voltage of the first BJT and the base emitter voltage of the second BJT.
