摘要
Bandgap Voltage Reference circuits configured to produce reference voltages with both voltage offset and a voltage temperature slope are disclosed. By generating the voltage offset from a temperature-independent current, the voltage offset of the reference voltage may be temperature-independent, while generating the voltage temperature slope from a temperature-dependent current allows the voltage temperature slope to vary with temperature. To ensure that the voltage offset remains independent from the voltage temperature slope, an apparatus is disclosed for orthogonal trimming of voltage offset and voltage temperature slope.
