Patent ID: 7990202

Claim:
A system for driving a bipolar junction transistor, the system comprising: a first transistor including a first gate, a first terminal, and a second terminal, the first gate being configured to receive a first control signal; a second transistor including a second gate, a third terminal, and a fourth terminal, the second gate being configured to receive a second control signal, the second control signal being separate from the first control signal; a first resistor including a fifth terminal and a sixth terminal, the fifth terminal being connected to the first terminal, the sixth terminal being biased to a first predetermined voltage; and a second resistor including two terminals, the second resistor not being a part of any transistor; wherein: the fourth terminal is biased to a second predetermined voltage; the second terminal and the third terminal are connected at a node; one of the two terminals is coupled to the node; the other one of the two terminals is biased to the second predetermined voltage; the node is connected to a base for a bipolar junction transistor; the first control signal and the second control signal each are related to a pulse-width-modulated signal for a power converter; the power converter includes a primary winding associated with a current; and the bipolar junction transistor is configured to function as a switch related to the current.
