ABSTRACT:
For coupling to a high speed logic device, a monolithic IC regulator is provided which is fully compensated for temperature and for variations in supply voltage. The temperature compensation is accomplished by the proper matching of resistances and current densities in transistor-diode circuitry and the compensation for variations in voltage supply is accomplished by coupling a feedback amplifier section to the regulator, the resistances and diodes of which are carefully matched to the resistances of the regulator so that the feedback amplifier section, being dependent only on such matching, is responsive over large fluctuations of supply current. The feedback amplifier section is also provided with a circuitry which slightly imbalances the amplifier section relative to the regulator so that current will flow through the shunt transistor of the regulator and by further matching the current density of the shunt transistor of the regulator with the current density of a component of the current mode logic device, the desirable characteristics for high speed digital logic functions are accomplished.
