  • Reduction of temperature dependence of a reference voltage
    Patent number: 7821331
    Abstract: An apparatus and a method to reduce temperature dependence of a reference voltage have been presented. In one embodiment, the method includes generating a reference voltage associated with a difference between a first threshold voltage of a first transistor and a second threshold voltage of a second transistor. The method may further include biasing the first transistor and the second transistor at a predetermined ratio of currents of the first and the second transistors to reduce temperature dependence of the reference voltage.
    Type: Grant

  • Leptin binding domain compositions and methods thereto
    Patent number: 7320868
    Abstract: The present invention provides compositions and methods relating to avian leptin receptor binding domains. The present invention demonstrates that these compositions are useful for detecting the presence of leptin in a sample and distinguishing free leptin from bound leptin in multiple species. Methods and kits are presented for determining free leptin in a sample from an individual by assaying a sample for the binding of leptin to an avian leptin receptor binding domain, and detecting the bound leptin by using a labeled anti-leptin antibody.
