Abstract
In an amplification device, an amplification unit has a transistor and amplifies a signal that is input. A control unit applies, when a power source is turned on, a pinch-off voltage to a gate of the transistor before applying a drain bias voltage to a drain of the transistor and then applies a gate bias voltage to the gate of the transistor.
Claims4
An amplification device that amplifies a signal, comprising:
- an amplification unit having a transistor and configured to amplify the signal;
- and
- a control unit configured to, when a power source is turned on, apply a pinch-off voltage to a gate of the transistor before applying a drain bias voltage to a drain of the transistor and then to apply a gate bias voltage to the gate of the transistor.
An amplification method of an amplification device that amplifies a signal, the method comprising:
- applying, when a power source is turned on, a pinch-off voltage to a gate of a transistor in an amplification unit configured to amplify the signal;
- and
- applying a drain bias voltage to a drain of the transistor and a gate bias voltage to the gate of the transistor after applying the pinch-off voltage.
