Patent US 4,016,435

A current stabilizing arrangement which includes a three-terminal circuit with an input terminal and an output terminal, at which output terminal a current with a negative temperature coefficient appears, while a constant current is applied to the input terminal. The arrangement further comprises a current source circuit, which supplies a current with a positive temperature coefficient and a squaring circuit to which a current is applied which is proportional to the current of the current source circuit, and whose output current, added to the output currents of the current-source circuit and of the three-terminal circuit, results in a temperature independent current. The temperature independent current thus obtained is applied to the input of a current mirror circuit, whose output current is fed to the input terminal of the three-terminal circuit.
