Abstract
Techniques and circuits for high speed switching of transistors are provided. These techniques and circuits switch an output device while varying the drive current to the output device in proportion to the output current through the output device. In addition, these techniques and circuits provide a switching circuit with substantially no quiescent currents. This is accomplished by sampling the output current conducted by the output device and using the sample as a signal to drive either the output device fully ON or to switch the output device fully OFF.
