The present disclosure relates to a capacitively-coupled non-uniformly distributed amplifier (NDA) having an input line and an output line that are coupled to one another through an input network and DA segments. The input network includes a group of capacitive elements coupled between the input line and the DA segments to extend a gain-bandwidth product of the NDA. The output line includes inductive elements, and since the NDA is non-uniformly distributed, an inductance of each inductive element decreases moving from an input end of the output line to an output end of the output line to compensate for decreasing impedance along the output line. To compensate for phase velocity variations along the output line, a capacitance of each capacitive element that is coupled to the input line decreases moving from an input end of the input line to an output end of the input line. |
