U niversity of S outhern C alifornia USC Viterbi School of Engineering Ming Hsieh Department of Electrical Engineering EE 541: Homework Assignment #05 Fall, 2010 Due: 10/07/2010 Choma Problem #20: A linear feedback amplifier, whose equivalent circuit is the topology embedded within the dashed box in Figure (P20), is terminated at its output port in a resistance, R L , and is driven by a signal source whose Thévenin equivalent resistance is R S . When meas- ured with respect to a characteristic impedance of R o , the reflection coefficients of the load re- sistance, R L , the source resistance, R S , and the feedback resistance, R F , are ρ L = 9/11 , 0 , and ρ F = 19/21 , respectively. If g m R L = 10 , find the input port reflection coefficient and all scattering pa- rameters, where it is understood that the scattering parameters are measured with respect to the reference resistance, R o . + R F R S g V m1 R L V 1 I 1 V 2 V S Figure (P20) Problem #21: A lossless lattice network is interposed between a signal source whose Thévenin resistance is R s
