  • Beta enhanced voltage reference circuit
    Patent number: 8760220
    Abstract: A beta enhancement circuit includes a current source connected in series with a transistor between two voltage supply lines. In an embodiment, the voltage supply lines are configured for connection to a power source and ground potential. A resistor device is connected between a control terminal of the transistor device and one of voltage supply lines. A value for the resistor device is selected based on one or more process dependent parameters of the transistor.
    Type: Grant
