ABSTRACT:
A bootstrap driver circuit directly coupled to a complementary pushpull output circuit and including a field effect transistor with current unsaturated triode vacuum tube characteristics. The output of the pushpull output circuit is coupled to the drain and source circuits of the driver field effect transistor by means of capacitors. The present invention also discloses a predriver circuit which uses a current unsaturated type field effect transistor and can be directly coupled to the driver circuit.
