Chapter 5 – Impedance Matching and Tuning

3/25/2009 section 5_1 Matching with Lumped Elements 1/3 Jim Stiles The Univ. of Kansas Dept. of EECS Chapter 5 Impedance Matching and Tuning One of the most important and fundamental two-port networks that microwave engineers design is a lossless Matching network (otherwise known as an Impedance transformer). HO: Matching NETWORKS Q: In microwave circuits, a source and load are connected by a transmission line. Can we implement Matching networks in transmission line circuits? A: HO: Matching NETWORKS AND TRANSMISSION LINES Q: These Matching networks seem too good to be true can we really design and construct them to provide a perfect match? A: We can easily provide a near perfect match at precisely one frequency. But, since lossless Matching and transmission lines are made of entirely reactive elements (not to mention the reactive components of source and load Impedance ), we find that changing the frequency will typically unmatch our circuit!

Closed and Open Loop Gain lecture - ITTC

* The closed-loop gain is determined by two resistor values, which typically are selected to provide significant gain (A vo >1), albeit not so large that the amplifier is easily saturated. * Conversely, the open-loop gain (-A op) obviously does involve the op-amp gain. Moreover, as in this case, the open-loop gain of a feedback amplifier
