摘要： An amplification circuit includes a first amplifier circuit and a second-stage amplifier. The second-stage amplifier is connected to the amplifier to form a multi-stage amplification circuit. The first amplifier circuit includes a first-stage amplifier and a bypass circuit. The bypass circuit includes a first transistor. A first end of the first transistor is coupled to the input end of the first amplifier circuit, a second end of the first transistor is coupled to the output end of the first amplifier circuit, and a third end of the first transistor is coupled to a supply voltage. The first end of the first transistor is further coupled to a first control terminal to receive a control signal for controlling a bias voltage of the first transistor, so as to make the amplification circuit work in different operation modes.

摘要： A system to program parameters of one or more stages of a transimpedance amplifier (TIA) in an optical sub-assembly (e.g. TO-can package) is disclosed. With this invention, users have the option/flexibility to discretely program any of the stages of the TIA after production of the sub-assembly, i.e. they can still change the TIA settings once the TIA has been installed in a system and the system is in use.

摘要： A coaxial amplifier having at least one electron beam is provided. The amplifier may include a conductive rod, a plurality of parallel discs on the rod, a cathode array for producing at least one electron beam. When a plurality of electron beams are formed they are arranged in an annular configuration around said rod and disks, and directed along said rod and coaxially thereof. A first waveguide may apply electromagnetic wave energy to one end of said disc and rod assembly to induce propagation of said energy along said assembly. A second waveguide may extract the amplified electromagnetic energy from the other end of the disc and rod assembly.
