ABSTRACT:
A temperature-insensitive reference voltage for an integrated circuit is created by positioning a reference voltage generator circuit proximate to a temperature control structure formed directly on the chip. The temperature control structure utilizes the Peltier Effect to translate an applied voltage into a change in temperature. The voltage applied to the temperature control structure is regulated by a temperature regulator circuit. Both the temperature regulator circuit and the reference voltage generator circuit are formed from standard IC components. In response to detected changes in ambient temperature, the temperature regulator circuit communicates a control voltage to the temperature control structure. The thermal environment, and hence voltage output, of the voltage reference generator circuit is thus stabilized by Peltier heating and cooling relative to changes in ambient temperature.
