    • A constant current flowing through a first depletion transistor whose gate and source are connected to each other is caused to flow through a second depletion transistor having the same threshold as the first depletion transistor, to thereby generate a first voltage between a gate and a source of the second depletion transistor. The constant current of the first depletion transistor and a constant current flowing through a third depletion transistor whose gate and source are connected to each other are caused to flow through a fourth depletion transistor. A threshold of the fourth depletion transistor is the same as that of the third depletion transistor but different from that of the first depletion transistor, and hence a second voltage is generated between a gate and a source of the fourth depletion transistor. A reference voltage is generated based on a voltage difference between the first and second voltages.

    • A circuit and method for a bandgap voltage reference operating at 1 volt or below is disclosed, wherein the operational amplifier (A1) drives resistors (R2, R3) only so that both the flicker noise contribution and the process sensitivity due to the conventional metal oxide semiconductor (MOS) devices used as a current mirror within the proportional-to-absolute-temperature (PTAT) loop are eliminated. Two symmetric resistive divider pairs formed by (R1A/R1B, R2A/R2B) are inserted to scale down both the base-emitter voltages (VEB1, VEB2) of bipolar transistors (Q1, Q2) and the PTAT current (IPTAT) so that an output reference voltage (VREF) becomes scalable. Proper bias currents through transistors (M3, M4), which are used to bias (Q1, Q2) and (R1A/R1B, R2A/R2B) respectively, are produced by an additional V-I converter (319) using VREF itself, resulting in a final process, voltage and temperature (PVT) insensitive output reference voltage.
