An improved bias generator provides a bias voltage output which is a function of an input current Iprog and provides a bias current to a preselected load which tracks the input signal independently of temperature. The amount the bias voltage output changes with temperature is determined by (1) V(T, Iprog), a voltage-current temperature dependent function of the base-emitter voltage drop of at least one transistor and (2) X, a scalar which is easily provided by setting the ratio of two resistors. The generator can therefore be easily constructed for particular circuit loads which include at least one semiconductive junction such that the biasing current through the load will be substantially independent of temperature.
