ABSTRACT OF THE DISCLOSURE A bias generator is disclosed for providing a bias voltage to a circuit. The generator comprises signal generating means for generating the bias voltage. The signal generating means is setting the level of the bias voltage so that the bias voltage varies as a function of the change of the voltage drop across the base-emitter junction of a semiconductive transistor with variations in ambient temperature. The means for setting the level of the bias voltage includes means for defining the first reference voltage, means for defining a second reference voltage, means for providing a difference voltage in response to a comparison between and first and second reference voltages, means for generating a multiple signal equal to the difference signal multiplied by a constant k, and means for summing a multiple signal with the first reference signal so as to form the biasing voltage. The difference voltage is related to the change in voltage drop across the base-emitter junction of least one semiconductor transistor as a function of the change of temperature.
