<p>A driver (Highside Driver, Lowside Driver) adapted to drive each of final transistors (MH,Ml,Mpower) included in a power amplifier, the driver includingra first plurality of switches (Mpslow,Mpmoderates, Mpfast) having their respective main current channels coupled between a bias voltage terminal (Vddx) and a control electrode (Vgsh, Vgst, Vgate) sches (Mpslow,Mpmoderate, Mpfast) being selcetivly turned ON for enabling approgressive charging of the respetive control electrode (Vgsh, Vf sl, Vgste) of the final transistors (MH,ML,Mpower), a second plurality of switches (Mnslow,Mnf ast) having their respective main current channels coupled between another bias voltage terminal (Vsource) and the control electrode ( (Vgsh, Vgsl, Vgate) of the respective final transistors (Mh,ML,Mpower), said second plurality of switches (Mnslow,Msfast) being selctivly switched ON until a current through the respective final transistors (MH),ML,Mpower) changes its polarity,</p> |
