問題詳情

5.(20%) The circuit of Fig. 5 utilizes two MOSFET's whose bias details are not shown and a 50Ω coaxial cable. Transistor Q1 operates as a CS amplifier and Q2 as a CG amplifier. For proper operation, transistor Q2 is required lo present a 50Ω resistance to the cable. That is, the inpul resislance of Q2 is 50Ω. Assume llie transistors are well biased here. Whal must gm2 be? What value of RD is required to provide 1V pulses at I he drain of Q2?
