Abstract
A microcontroller includes a reference voltage generator circuit having a first transistor coupled as a diode, a second transistor coupled as a diode, a first variable resistor, an operational amplifier having a first input connected to the first transistor via the first variable resistor, and a second input connected to the second transistor, and second variable resistor having a first terminal connected to the second transistor and to the second input of the operational amplifier. A current mirror is controlled by an output of the operational amplifier and configured to replicate the current proportional to an absolute temperature of the second variable resistor. A current copier branch is connected to the second transistor via a switch, the current copier branch being configured to replicate the current proportional to the absolute temperature of the second variable resistor and inject the current through the second transistor.
