Supply circuit, especially for Avalanche Photo Diodes. The supply voltage is generated in a temperature-independent voltage source (VS1) and a temperature-dependent voltage source (VS2), both connected to a voltage amplifier (A1, A2), the output voltages being added to one another. The last-mentioned voltage supply comprises a temperature-independent voltage source (A3) whose output voltage is subtracted from the output voltage of a partially temperature-dependent voltage source in the form of a temperature-sensitive impedance, such as a diode (D) in the forward direction, connected to a current source (CS). <IMAGE>
