POWER AMPLIFIER

摘要

The invention refers to a power amplifier comprising a first transistor (M1) having a first conducting channel and a second transistor (M2) having a second conducting channel, the first conducting channel being coupled in series with the second conducting channel and further coupled to an output node (2). The power amplifier further comprises a first driver circuit (10) coupled to a first control electrode of the first transistor (M1), a second driver circuit (20) coupled to a second control electrode of the second transistor (M2) and a bootstrap capacitor (C<SUB>boot</SUB>) coupled between the output node (2) and a node (1) of the first driver circuit (10) and a first sensor circuit (40) coupled in parallel to the bootstrap capacitor (C<SUB>boot</SUB>).
