The schematic shows a scheme for coupling and amplifying


The schematic shows a scheme for coupling and amplifying ahigh-frequency pulse signal. The circuit utilizes twon-channel MOFETs whose bias details are not shown and a 50 ohmcoaxial cable connecting the drain of Q1 to the source of Q2. Transistor Q1 operates as a CS amplifier and Q2 as a CGamplifier. For proper operation, transistor Q2 is requiredto present a 50 ohm resistance to the cable. When thecable is properly terminated, its input resistance is 50ohms.
A. What must gm2 be?
B. If Q1 is biased at the same point as Q2 what is theamplitude of the current pulses in the drain of Q1?
C. What is the amplitude of the voltage pulses at the Drainof Q1?
D. What value of RD is reqired to provide 1-V pulses at the Drain of Q2?
