The invention relates to a driving circuit implementation device for improving dynamic performance of a power tube. The driving circuit implementation device comprises an input signal source, a phaseinverter, a first integrated circuit, a second integrated circuit, fourteen resistors, a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a fifth capacitor, a first transistor, a second transistor, a third transistor, a first power supply, a second power supply, a third power supply (external power supply), first reference ground and second reference ground. By increasing the conduction speed of an N-channel enhanced MOSFET tube, the effects of reducing the switch loss, increasing the conduction speed and improving the dynamic response performance are achieved. The power tube driving circuit implemented by the invention is mainly applied to the field of a linear power supply, a switch power supply or an electronic load requiring a power field-effect transistor asan energy consumption component, the response speed and the dynamic loading response performance of the power tube can be effectively changed, and thus, the driving circuit has a wide application prospect.
