ABSTRACT:
An amplifier includes an amplifier input and an amplifier output. A gain cell is coupled between the amplifier input and the amplifier output and provides gain. The gain cell includes an input device to the amplifier input for reducing input capacitance and resistive losses, and an output device coupled to the amplifier output for reducing output resistive losses. The gain cell can further include a feedback device coupled to the gain cell output for stabilizing the gain cell. The gain cell input includes a common-collector bipolar transistor and the gain cell output includes a common-base bipolar transistor in series with a common-emitter bipolar transistor. Because of the low input and output resistive losses and a low input capacitance, the gain cell can be incorporated into a distributed amplifier having numerous stages without decreasing gain or bandwidth performance.
