Optimization of Matching Network in Cadence

时间:04-07 整理:3721RD 点击:
Hi All
As a part of understanding how to optimize matching networks in cadence I am designing a matching network to match 10 ohm load to 50 ohms source at 6Ghz. I am using simple L matching network and I know all the equations required. I come up with the required values of L and C. Simulation shows real part of input impedance to be 50 ohms when I use ideal inductor and capacitor. Now I keep ideal capacitor and use inductor provided by tsmc 0.13um process. As expected (because of component Q) real part of input impedance is dropped to 45 ohms. I want to know how I can use cadence to automatically optimize this or any other matching network. I found that ADE GXL can be used for optimization but when I read the manual I thought it can be used for only Anlog Circuits (matching devices etc). Please let me know how I can use cadence to do the optimization of matching networks.

Thanks in Advance

You should first define your variables ( L and C values in a range )and then define your goals in ADE and then do your optimization.

Hi
Thanks for your reply. Do you have any tutorial describing how to do this?

Thanks again
