Unformatted text preview: 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 g m W m mS g / 2 m i g R / . 1 gd C fF g gs W m fF C / 5 . g ds W m mS G / 1 . Note that because of numerical problems in ADS, it may be necessary to add a nonzero gd C ; keep it small enough to not change the simulations ! Background:Bilateral Device model. g m W m mS g / 2 m i g R / . 1 g gd W m fF C / 1 . g gs W m fF C / 5 . g ds W m mS G / 1 . Problem 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 g W =100 microns for the unilateral device model, calculate the following by hand: insertion power gain, operating power gain, available power gain, maximum available...
