ABSTRACT:
In a push-pull power amplifier having an end stage (10) in which two power transistors (ML, MH) are connected in series, a dead time is normally used to ensure that the power transistors do not conduct simultaneously. The invention provides an end stage in which the dead time can be omitted. This is achieved by dimensioning the driver circuits (11, 12) in such a way that during switching the control voltages (Vgh, Vgl) of the power transistors cross their threshold level (VT) substantially simultaneously.
