Optimization of Matching Network in Cadence

nadroit

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

      Thanks for the reply. I know how to do .sp analysis with ADE XL. I was trying to use optimization in ADE GXL (local and global) to tune the values of L and C in L matching network. I could run the simulation with out errors but GXL did not give me optimized values. I searched the GXL documentation and found out the optimization was used for lot of Analog Designs (eg optimising opamp gain etc). My question is can I use the optimization for RF applications like fine tunning the matching netwrok? if yes do you have any tutorial which I can follow?

    Thanks
