Summary:A termination network simultaneously provides a voltage-limited output direct current (dc) bias and termination of a broadband distributed amplifier operating down to an arbitrary low frequency. It is capable of being fabricated in a single Integrated Circuit (IC) chip, without the excess power dissipation associated with biasing through a termination resistor, and without the use of external inductor networks. It also limits the maximum dynamic voltage swing on the outputs of the active gain devices used within the distributed amplifier, so as to increase the reliability of the distributed amplifier under large signal over drive conditions.
