    • In one embodiment, a circuit comprises an adaptive predistorter and a nonlinear element coupled to an output of the predistorter. The predistorter is operative to predistort an input signal according to predistortion control parameters at a given sampling rate. The circuit further comprises an identification unit and a translation unit. The identification unit identifies nonlinearity parameters representing the nonlinearity of the nonlinear element by sampling the output of the nonlinear element at an identification sampling rate lower than twice a bandwidth at the output of the nonlinear element. The translation unit translates the identified nonlinearity parameters into the predistortion control parameters. Other systems and methods are disclosed.

    • The invention relates to a power switch arrangement having a semiconductor power switch connected by its load path serially in a load circuit, and a clamping circuit, which is connected between a control electrode terminal and a load-side electrode terminal of the semiconductor power switch. Upon the turn-off of the semiconductor power switch, a clamping voltage is set across the load path thereof. The power switch arrangement additionally has a temperature estimator, which supplies an estimated value corresponding to an instantaneous peak temperature of the semiconductor power switch that occurs directly after the turn-off instant of the semiconductor power switch. The power switch arrangement also has a control device that generates, after the turn-off instant a control signal that is fed to the clamping circuit, if the estimated temperature value has a magnitude that corresponds to a temperature value of the semiconductor power switch that exceeds the maximum desired temperature of said semiconductor power switch. The control device controls the clamping circuit in such a way that the latter sets the clamping voltage in such a way that the protected peak temperature does not exceed the maximum desired temperature, a minimum voltage value of the clamping voltage not being exceeded, which value is determined in such a way that the change in the load current through the semiconductor power switch with respect to time does not become positive and is subsequently increased, first gradually and then very rapidly again.
