Abstract
This paper studies application of a semi-active dual loop feedback network in an ultrawideband low-noise amplifier which has been realized in a 130-nm bulk digital CMOS process. The proposed simple feedback connection is shown to improve amplifier stability and to increase isolation, with no discernible extra cost. Measurement results support the stated benefits with stable amplifier operation in all measurement points.
