摘要 |
To eliminate the temperature dependency of the quiescent current of a power transistor (1), the gate bias voltage of the power transistor (1) is controlled by means of the output voltage of a biasing transistor (3) residing on the same silicon chip as the power transistor (1), and by interconnecting the gate (G3) and drain (D3) of the biasing transistor (3) and feeding it with a constant current (IB) from external circuitry. |
