description The utility model provides a bipolar amplifier, which comprises a main audion, a blocking condenser and a biasing circuit. The upper end of the blocking condenser is connected with a base electrode of the main audion, an emitting electrode of the main audion is grounded, and a collecting electrode of the main audion is connected with the voltage output end. The biasing circuit is connected with the base electrode of the main audion and comprises a ground resistor, a current signal source and two audions, one end of the current signal source is connected with a base electrode of a second audion, and a base electrode of a first audion is connected with the base electrode of the main audion. A base electrode of the first audion is further connected with the second audion, the other end of the ground resistor is grounded, and an emitting electrode of the first audion is grounded. By means of the bipolar amplifier, the biasing circuit can amplify the safe working range of the bipolar amplifier.
