Abstract:
One example includes a circuit that includes a transistor control circuit having an input and an output adapted to be coupled to the output of the transistor control circuit and can provide a slew-rate compensation voltage proportional to a slew-rate of a control voltage of the transistor. A reference voltage source can be coupled to the slew-rate compensator to provide a reference voltage at the output of the reference voltage source, the slew-rate compensator configured to add the slew-rate compensation voltage to the reference voltage to provide an adjusted reference voltage at the output of the slew rate compensator. A reference comparator having a first input, a second input and an output is coupled to the input of the transistor control circuit. The first input can be coupled to the control terminal of the transistor, and the second input can be coupled to the output of the slew-rate compensator.
