7.120 Figure P7.120 shows a scheme for coupling andamplifying a high-frequency pulse signal. The circuit usestwo MOSFETS whose bias details are not shown and a 50-Scoaxial cable. Transistor Q, operates as a CS amplifier andQ, as a CG amplifier. For proper operation, transistor Q,is required to present a 50-N resistance to the cable. Thissituation is known as "proper termination" of the cable andensures that there will be no signal reflection coming backon the cable. When the cable is properly terminated, its inputresistance is 50 2. What must g be? If Q, is biased at thesame point as Q,, what is the amplitude of the current pulsesin the drain of Q,? What is the amplitude of the voltagepulses at the drain of Q,? What value of R, is required toprovide 1-V pulses at the drain of Q,?
