IPC: H03K19/00
Filed: 1989-12-22
Abstract: PURPOSE:To obtain a bias voltage supply circuit, which can supply a stable bias voltage, by using an injection resistor to be operated in a saturated area and an injection resistor to be operated in a linear area. CONSTITUTION:A first injection resistor RS is provided to be operated in the saturated area while connecting one end to a high voltage power source VDD and a second injection resistor RL is provided to be operated in the linear area while connecting one end to a low voltage power source VSS. Then, the other ends of the first and second injection resistors RS and RL are respectively connected each other and a voltage to be generated at the connecting point is impressed to the gate of an FET Q1. Therefore, for the injection resistor RS connected to the high voltage power source side, even when a power supply voltage is fluctuated, current flow is constant and at the both ends of the injection resistor RL operating in the linear area, connected to the low voltage power source side, constant potential difference is generated. Thus, since the constant potential difference generated here is used as the bias voltage, the stable bias voltage supply circuit can be constituted.
