A synthesis-oriented conditional stability criterion for microwave multidevice circuits with complex termination impedances

In this work, a new conditional stability criterion for multidevice circuits is proposed, in order to guarantee stability in spite of input and output termination variations in regions surrounding complex nominal values. A check of this criterion can be implemented in a commercial CAD environment, a...

Description
Summary:In this work, a new conditional stability criterion for multidevice circuits is proposed, in order to guarantee stability in spite of input and output termination variations in regions surrounding complex nominal values. A check of this criterion can be implemented in a commercial CAD environment, and this allows imposing stability from within an optimization routine. A design methodology to synthesize multidevice circuits with complex termination impedances, which are stable under both process parameters and terminations variations, is proposed.
