  • 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...

  • OSCILLATOR DESIGN

    I am new to AMS language and design and I am trying to model an oscillator with the following features : a. The oscillator operates at a default freq of say 32Khz, with tuning applicability from 20Khz to 50Khz. b. The oscillator operates in two power domains, one of 3.3v and other of 1.2v. c. When the...

  • Mixed-Signal Gets Clear Message in China

    While most of my colleagues in the US were taking a nice break during the July 4 th week, a small group of people including me was on the road for a mixed-signal Tech-on-Tour in China. There was some debate internally on whether designers in China would be interested in such a topic. What we had experienced...
