  • Self-referenced control circuit
    Patent number: 5804958
    Abstract: A voltage control temperature compensated circuit for coupling to a supply that provides a supply voltage at first (102) and second supply nodes (103) and the voltage control circuit for generating and regulating an output voltage (VREG). The voltage control circuit includes an output device (18) coupled to the first and second supply nodes for generating the output voltage and a base coupled bipolar pair controller (15 and 14) coupled to the first and second supply nodes for generating an internal high-side (106) voltage reference (104) and for regulating the output voltage to compensate for changes from the desired response between the output voltage and the internal reference voltage.
