Title: spectre RF simulation Post by hala youssef on Jan 8th, 2010, 6:46am Where can I write the -E command to use spectreRF simulation to run the ac analysis of switched capacitor circuit? |
Title: Re: spectre RF simulation Post by Ken Kundert on Jan 8th, 2010, 9:34am Presumably you are asking how to apply spectre to Listing 1 of http://www.designers-guide.org/Analysis/sc-filters.pdf. Use ... Code:

Title: Re: spectre RF simulation Post by hala youssef on Jan 12th, 2010, 4:11am Hi, I want to know where can I write this command "spectre -E tah.ckt "? Also, is it mandatory to describe the circuit using verilogA or it is possible to use schematic view for the circuit description? Additional information: I am trying to design SC BPF and I need to make the ac analysis for my circuit. |

You have to write Verilog-A block as Verilog-A code. But for instantiation of it as test bench netlist of spectre with analysis statements and signal source statements, you can do it by either text editor or schematic view. |
Title: Re: spectre RF simulation Post by hala youssef on Apr 7th, 2010, 11:46am Sorry, my question was not accurate. My question is how can I use the analog environment in cadence to make the ac analysis of switched capacitor circuit? |

This is how I do it with my BPF: 1. On schematic put voltage source on the input and set PAC magnitude to 1. Do not forget to put clock source. 2. In ADE choose PSS and set parameters - clock is from shematic - set fundamental to auto calculate - number of harmonics 0 - tstab to what you need 3. In ADE choose PAC and set parameters: - PSS beat freq should be set automatically - start, stop and others like for AC - maximum side bands 0 Start the simulation. BR |
