Abstract
In some examples, a circuit comprises a first field effect transistor (FET) having a first gate adapted to couple to a reference voltage source, a first source coupled to a first current source, and a first drain coupled to a second current source. The circuit comprises a second FET having a second gate coupled to the first drain, a second drain coupled to the first current source, and a second source coupled to a first resistor. The circuit comprises a third FET having a third gate adapted to couple to a feedback loop of a voltage converter, a third source coupled to a third current source, and a third drain coupled to a fourth current source. The circuit comprises a fourth FET having a fourth gate coupled to the third drain, a fourth drain coupled to the third current source, and a fourth source coupled to a second resistor.
