Chapter 5 – Impedance Matching and Tuning - ITTC

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.

Closed and Open Loop Gain lecture - ITTC

www.ittc.ku.edu

* 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
