Question
7.120 Figure P7.120 shows a scheme for coupling and amplifying a high-frequency pulse signal. The circuit uses
two MOSFETS whose bias details are not shown and a 50-2coaxial cable. Transistor Q1 operates as a CS amplifier
and Q2 as a CG amplifier. For proper operation, transistor Q2 is required to present a 50-2 resistance to the cable.
This situation is known as “proper termination" of the cable and ensures that there will be no signal reflection
coming back on the cable. When the cable is properly terminated, its input resistance is 50 2. What must gm2 be? If
Qi is biased at the same point as Q2, what is the amplitude of the current pulses in the drain of Q1? What is the
amplitude of the voltage pulses at the drain of Q1? What value of RD is required to provide 1-V pulses at the drain
of Q2?
