Abstract
Provided herein are multi-stage broadband amplifier configured to achieve a high gain-bandwidth product in a non-distributed architecture and methods for designing the same. The broadband amplifier can include an input stage having a broadband matching unit and an input buffer unit, a gain stage having an RLC network and a amplifier unit and an output stage having a common collector amplifier and an RC compensation unit.
Claims11
A broadband amplifier having a non-distributed configuration, comprising:
- an input stage comprising a broadband matching unit coupled with an input buffer unit, the input stage configured to receive an input signal, wherein the broadband matching unit comprises an artificial transmission line;
- a gain stage coupled with the input stage, the gain stage comprising an amplifier unit coupled with an RLC network;
- and
- an output stage coupled with the gain stage, the output stage comprising a common collector amplifier, the output stage configured to output an output signal representative of an amplified input signal.
