1 ECE 145a /218A problem set : Reactively matched ampliers: mostly unilateral design. Background: Unilateral Device model. We will assume a highly simplified device model as to the right, with gmWmmSg/2migR/0.10gdCfF ggsWmfFC/5.0gdsWmmSG/1.0Note that because of numerical problems in ADS, it may be necessary to add a nonzero gdC; keep it small enough to not change the simulations ! Background:Bilateral Device model. gmWmmSg/2migR/0.1ggdWmfFC/1.0ggsWmfFC/5.0gdsWmmSG/1.0Problem 1: For the unilateral device model, compute by hand the maxium available power gain and the short-circuit current gain as a function of frequency. Problem 2: For a 50 Ohm generator and load, at a frequency of 50 GHz, and taking gW=100 microns for the unilateral device model, calculate the following by hand: insertion power gain, operating power gain, available power gain, maximum available power gain. Simulate these in ADS and compare with hand calculations.
