摘要 |
An amplifier device, including: at least one input contact, an amplifier section for amplifying a signal presented at said input contacts whereby an amplified signal is obtained; said amplifier section being connected to said input contact; a bias current source connected to said amplifier section for providing a bias current which at least partially controls the gain of the amplifier section, at least one output contact connected to the amplifier section, for receiving the amplified signal from the amplifier section and transmitting the amplified signal further.
