Complementary metal-oxide-semiconductor (CMOS) voltage reference generator

A voltage generation circuit that receives an input control current and outputs a reference voltage (VREF), the voltage generation circuit comprising:

• a first circuit including a first transistor and a second transistor connected in series between a first node receiving the input control current and a supply node;
• a second circuit including a first resistor, a second resistor and a third resistor connected in series between the first node and the supply node,
• wherein the input control current is divided between the first circuit and the second circuit;
• a reference node that outputs the reference voltage (VREF) and that is connected to the first transistor of the first circuit;
• a second node located between the second resistor and the third resistor and in electrical communication with the second transistor;
• and
• a current supply circuit connected to the second node and providing a compensation current that influences the reference voltage (VREF) to account for changes in operating temperatures of the voltage generation circuit.
