| 发明名称 | Amplification circuit | ||
| 摘要 | An amplification circuit includes a first power supply; a first bipolar transistor whose collector is connected to the first power supply; a first resistor one terminal of which is connected to an emitter of the first bipolar transistor; a second bipolar transistor whose collector is connected to the other terminal of the first resistor; a second power supply; a third bipolar transistor whose collector is connected to the second power supply; a second resistor one terminal of which is connected to an emitter of the third bipolar transistor; and a fourth bipolar transistor whose collector is connected to the other terminal of the second resistor. An emitter of the second bipolar transistor is directly connected to an emitter of the fourth bipolar transistor, thereby becoming an output terminal. | ||
