Title: RF CMOS Power Amplifier Design - Virtuoso Post by Dshoter on Mar 11th, 2015, 10:31am Hi. I'm trying to design a CMOS Class B PA using Virtuoso. I designed my output matching network for maximum gain.. but when I'm simulating S-Param, Harmonic Balance and doing Periodic States Simulations etc, I have to use a Port, and It comes with 50Ohm resistence. My question is: it will have impact in my PA performance? Do I have to design a input matching network to obtain the correct results in Virtuoso? Thank you all for you attention. Best regards. |

Title: Re: RF CMOS Power Amplifier Design - Virtuoso Post by AdamAzzata on Sep 25th, 2015, 4:54am For simulation you do not need to design any impedance matching circuits for input and output. But if you add then the results will be better. For practical circuits you must add them. They are necessary for the proper functioning of your circuit. |
