Claim 4:
5. The amplifier device according to claim 3, wherein
the first bias power supply unit includes:
a first current amplifier circuit configured to generate a first amplified current by amplifying a first supply current supplied by the common constant-current power supply, and
a first constant-current power supply,

the second bias power supply unit includes:
a second current amplifier circuit configured to generate a second amplified current by amplifying a second supply current supplied by the common constant-current power, and
a second constant-current power supply,

the first bias power supply unit is configured to add the first amplified current to a first current draw drawn by the first constant-current power supply, and
the second bias power supply unit is configured to subtract the second amplified current from a second current draw drawn by the second constant-current power supply.
