Patent ID: 7411768

Claim:
A transistor active bridge circuit connectable between a pair of input lines and a pair of output lines, comprising: first and second field effect transistors of a first channel type, a source-drain path of said first field effect transistor connected in series with a source-drain path of said second field effect transistor to form a first series transistor combination connected across said input lines; third and fourth field effect transistors of a second channel type, a source-drain path of said third field effect transistor connected in series with a source-drain path of said fourth field effect transistor to form a second series transistor combination connected across said input lines; a voltage divider provided for each of said field effect transistors, said voltage divider comprised of a first resistor and a second resistor connected in series from a source of each said field effect transistor to one of said input lines; a bias voltage tap defined at a connection point between said first and second resistors connected to a gate of each of said field effect transistors; and a shoot-through protection circuit comprising at least one active device connected across a gate and a source of each of said first, second, third, and fourth field effect transistors.
