  • Temperature stabilized bandgap voltage reference circuit
    Patent number: 5712590
    Abstract: A voltage reference circuit includes at least a first and a second voltage supply having different operating temperature ranges. Output voltages of the two voltage supplies are compared and one of the supplies is selected to provide an optimum voltage reference.
    Type: Grant

    Date of Patent: January 27, 1998
    Inventors: Michael F. Dries, Benjamin L. Gingerich
  • CMOS Address buffer for a semiconductor memory
    Patent number: 4435791
    Abstract: An input circuit for applying a supply voltage to the input/output voltage nodes of a regenerative latch in response to date inputs. A reference transistor applies a portion of the supply voltage to one node and a data transistor applies the full supply voltage to the other node in response to a data input signal. Write transistors control the connection of the data and reference transistors to the supply voltage. A precharge circuit is connected to the voltage nodes.
