Abstract
A current having a high negative temperature coefficient can be tapped from a current source circuit connected as a loop out of two current mirror circuits and having a resistor. Furthermore, a current source circuit of this type made with CMOS technology has a high current requirement. The invention permits a reduction of these drawbacks by replacing the resistor with a connected capacitor.
