Temperature-independent current source circuit
A temperature-independent current source is provided, which includes a current source generating a current that is proportional to the temperature and a current source generating a current that is inversely proportional to the temperature. Values of the circuit elements are selected so that the currents of the current sources add up to a substantially temperature-independent current. Related current sources utilize dual-base Darlington bipolar transistors to generate a temperature-independent current.
