Abstract:
A circuit generates a reference voltage that is independent of temperature. The circuit is built on a substrate according to a CMOS technology, and includes a first stage for generating a first current proportional to temperature and a second stage for generating a second current inversely proportional to temperature. These first and second currents are summed in a resistor connected to a voltage distinct from the ground of the first and second stages and formed by the voltage of the substrate on which the circuit is built.
