  • Self-biasing circuit
    Patent number: 6249175
    Abstract: In a self-biasing circuit, a reference current having a positive temperature characteristic and a reference current having a negative temperature characteristic are generated using one NPN transistor. The temperature response of the circuit is corrected by generating a combined reference current that is the sum of the reference currents having positive and negative temperature characteristics with a low driving voltage at a low current in a simple circuit.
