Abstract
A temperature independent CMOS reference voltage circuit includes a CMOS current mirror circuit containing first and second CMOS transistors of a first polarity. A temperature compensation circuit is coupled to the CMOS current mirror circuit, and contains a first resistor, a second resistor, and third and fourth CMOS transistors of a second polarity. The third and fourth CMOS transistors are configured to operate substantially in a subthreshold region. One of the third and fourth CMOS transistors is diode connected.
