Abstract
This disclosure relates to a filter circuit for an output stage of an electronic circuit. The filter circuit includes a capacitor connected between a supply voltage and a first transistor. The first transistor is arranged as a diode connected transistor; a second transistor is connected to the first transistor so that the first and second transistors are arranged as a current mirror. The capacitor is connected to the first and second transistors and configured and arranged so that during operation the first transistor, the second transistor and the capacitor operate as a high pass filter.
