Apparently, not only good temperature coefficient and regulable output voltage, but also good temperature coefficient output current can be obtained by regulating some of the resistances. The input offset voltage can be restrained by this method also. The result of the emulator shows that the temperature coefficient of the band-gap voltage reference is 2.8 × 10^(-5)/K, and the PSRR is over 70 dB.
