Abstract:
A high-output amplifier, comprising:a bias circuit having a first bias circuit and a second bias circuit, said first bias circuit including a first transistor having one end connected to a first high-voltage-side source and the other end connected to a low-voltage-side source, said one end being connected to the control terminal of the first transistor, said second bias circuit including a second transistor having one end connected to a second high-voltage-side source, the other end connected to said one end of said first transistor, and a control terminal connected to said first high-voltage-side source; and a transistor amplifier having a control terminal connected to said one end of said first transistor, one end as an output terminal of said high-output amplifier, and the other end connected to the low-voltage-side source, wherein said one end of said first transistor is connected to a control terminal of said transistor amplifier via an LC component.
