Abstract
Disclosed is bandgap voltage reference generator having a programmable resistor. The programmable resistor can be programmed to provide a proper ratio between the PTAT current and the CTAT current to reduce the effect of process variations on the bandgap voltage. The bandgap voltage reference generator includes a calibration circuit that programs the programmable resistor.
