3) Design lumped LC matching networks and compare to (2).
5 Problem 4 Using this MOSFET model: a) Simulate S21, S11, S22 in dB magnitude vs. Frequency b) Design and place a 100 GHz lumped LC matcing networks at the input, and again Simulate S21, S11, S22 in dB magnitude vs. Frequency c) Keeping the input matching network in place, design and place a 100 GHz lumped LC matcing network at the output, and again Simulate S21, S11, S22 in dB magnitude vs. Frequency. d) We now increase C3 (Cgd) to 0.5 fF. Re-adjust the matching networks to obtain matched S11 and S22 at 100 GHz. What do you observe ? e) Increase Cgd to 5 fF and reduce Rg to 5 Ohms. Try to re-adjust the matching networks to obtain matched S11 and S22 at 100 GHz. Now what do you observe ?
6 Problem 5 Using the MSUB parameters of problems(1,2), design a quarter-wave line output matching network at 100 GHz. At the input, use a short-circuited high-impedance shunt line of 5 microns width to make the input impedance pure real, and then a quarter-wave series line to complete the input match.
