mixed signal design

  • Re: mixed signal simulation

    thanks for your valuable guidance.... sir, in my project i have designed one block in verilog.Now i need to integrate it to the remaining analog blocks. so i generate verilog netlist of the corresponding digital block. But after integrating it with analog block i need to check functional and transistor...

  • mixed signal simulation

    is it possible to simulate verilog netlist in cadence virtuoso?how to bind the standard netlist cell to the corresponding code?

  • Mathematical explanation for resistor mismatch parameters

    Can someone please provide the formulas for the mismatch parameters (used in DCMATCH analysis): mrl mrlp mrw mrwp mrlw1 mrlw1p mrlw2 mrlw2p. I could not find the corresponding equations in the Spectre manuals. Thanks!

  • Vhdl-ams beginner

    Hi, I'm really new in vhdl-ams, I write my firsts codes in this langage and I have some issues to understand some basics of this extension. My tutor want me to describe an analogic comparator and test it with a ramp waveform. A schema of this circuit is in attachment. I don't know how to connect...

  • Re: Switched Cap based System Noise Analysis

    Hi Andrew, Previously I gave some incorrect information. My flow is like that 1) Comparator sampling bandgap charge @ 400 Khz 2) Comparator sampling input charge @ 400 Khz but after 1. ( Phase lag ) 2) Caps are connecting disconnecting @ 2 Mhz Best Regards Abhishek

  • Re: Switched Cap based System Noise Analysis

    Hi Andrew, Following are the details- 1) Comparator goes to unity feedback and then openloop - 222.22k 2) There are some caps and they either get connected b/w input of comparator and Supply or Input of comparator and ground- 2MHz 3) There is one switched cap BGREF. When comparator goes in unity feedback...

  • Re: Switched Cap based System Noise Analysis

    Hi Andrew, Thank you for being always first to answer. I referred your attachment before putting my query. But this says, it takes only one clock. In my system multiple switchings are happening and that too at different rates. Pardon my ignorance if I am not able to understand the material you attached...

  • Switched Cap based System Noise Analysis

    Hi, I am very new to noise analysis when it comes to switched capacitor based system. In my system I have a comparator which goes into unity feedback mode with some frequency. I have also a capacitor which either connects from input of comparator and ground or input of comparator and input to be compared...

  • Re: AMS simulation with VCD input file

    Hi Andrew, Thanks for your reply. But I would like to make this thing into you attention that I am using VCD file with signalInfofile only for analog signals. So whenever I had to do it I did with spectre. It works all the time. My requirement was now to force few signals on the fly and that can be done...

  • Support for Low Power Mixed Signal Designs in Virtuoso Schematic-XL

    Why is There a Need for Low Power Solutions? With an increase in the demand for high-performance, multi-tasking systems-on-chips (SoCs) for communication and computing, the power requirements for these electronic chips have also greatly increased. There has been a surge in the production of portable...
