1. An apparatus comprising:
a first die including:
a first transistor having a first channel including a first material; and
a temperature coefficient resistor having a first terminal and a second terminal, the temperature coefficient resistor including a resistance dependent on a temperature of the first die;
a second die including:
a second transistor having a second channel including a second material;
a variable current source including an output, a first input adapted to be coupled to an adjustment device, and a second input coupled to a voltage supply node;
a first temperature sensor configured to measure a value indicative of a temperature of the second die; and
a second temperature sensor including:
a reference voltage coupled to the second terminal of the temperature coefficient resistor;
an amplifier including an output and including a first input coupled to the output of the variable current source and the first terminal of the temperature coefficient resistor; and
a third transistor including a first current terminal coupled to the voltage supply, a second current terminal coupled to an output voltage, and a control terminal coupled to the output of the amplifier; and
a package including the first die and the second die.
