Abstract:
Embodiments of the invention describe a reference current generator circuit having a core circuit that includes a first transistor in a first current path for conduct a first current and a second transistor in a second current path for conduct a second current. The second transistor has a threshold voltage that is different from the threshold voltage of the first transistor by at least 10%. The voltage differential between the first and second transistors generate a voltage across a resistive component coupled in series with the second transistor in the second current path.
