Abstract
A bandgap voltage reference circuit comprises a plurality of delta base-emitter voltage (ΔVbe) cells extending between first and second voltage rails in a serial arrangement. Each ΔVbe cell includes a transistor comprising a single first emitter connection and eight second emitter connections. The single first emitter connection of a second transistor in the serial arrangement is coupled to one of the eight second emitter connections of a first transistor in the serial arrangement, and one of the eight second emitter connections of the second transistor is coupled to the single first emitter connection of a third transistor in the serial arrangement to form an electrical path from the first transistor to the third transistor. A resistor is at a distal end of the serial arrangement. An output voltage across the resistor includes a sum of delta base-emitter voltages generated by the plurality of ΔVbe cells.
