Method and circuit for an operating area limiter |
摘要 |
The present invention relates to circuits and methods for limiting the operating area of a transistor in a constant current source. The circuits and methods use a detector and a driver to limit the operating area of a transistor. The detector and driver have parameters selected so that, when the voltage at the drain of the transistor satisfies a reference condition, the driver causes drain current of the transistor to decrease. The reference condition is determined relative to the maximum safe drain-to-source voltage at the design drain current of the constant current source.
