ABSTRACT:
A small voltage is generated in such a manner as to be related to the increment between a pair of semiconductor band gap related voltages. Such a voltage will be linearly related to absolute temperature and will be useful in compensating the temperature dependence of semiconductor integrated circuits. In addition, it will allow control of the gain (or attenuation) of transistor current mirrors to a high degree of precision. The circuit is configured so that the small voltage is controlled by integrated circuit area parameters and thus is readily controllable and reproducible using conventional manufacturing processes.
