摘要：

This paper relates to a feedback network for cascade amplifiers, which uses an active stage to feed signal back to a first Internal node at the output of the first amplifier stage of the cascade, and an optional feedback path through a resistor. The proposed simple connection Is shown to Improve amplifier stability and to Increase Isolation, with no discernible extra cost. First measurement results of an UWB LNA prototype circuit fabricated In a 130-nm digital CMOS process will be given to support stated benefits.
