    Closed: ADC internal Reference voltage

    Hi all,

    we are using ADS1015 ADC its 12 bit adc (Vadc/Vref)*4095= adc digital value.

    for analog inputs we can give a voltage anywhere between
    ±0.256 ±6.144 V.

    not able to do find the value...
  2. Closed: Re: Output of exors are showing x in EDA playground

    Thanks FVM. I have mistakenly considered the input's inA and inB as wire's ; i have rectified them it works now. :)
  3. Closed: Output of exors are showing x in EDA playground

    Hi all ,
    I've tried a simple EXOR verilog code along with test bench on the EDA playground, test bench is forced with inputs 00,01,10,11 respectively ;

    can anybody tell me why were not getting...

    Closed: FPGA and processors working

    Hi All,
    I was hoping to get some insight as to why FPGA's and Microprocessors are both used together on the same board.
    I would like to start from referring to some already existing FPGA-Processor...
  7. Closed: Re: How does feedback loop control the duty cycle of buck regulator

    Hi all Thanks for the replies;
    please find the attachment,

    the regulator is operated in current mode, it consists of an internal clock generator, error amplifier and current sense.
    I have 2...
  8. Closed: How does feedback loop control the duty cycle of buck regulator

    Hi All,

    While going through internal structure of a buck regulator, there was a feedback loop connected from the voltage divider circuit therein connected to a comparator and the input fed to the...
  9. Closed: Re: Why return path in PCB is as significant as signal path with an example

    Thanks Klaus !!

    I also have few Doubts while going through some PCB boards!!

    What does loop inductance got to do with a transmission line!! Will they be resonant at Certain high Frequencies ...
  10. Closed: Why return path in PCB is as significant as signal path with an example

    Hi
    It would be Helpful if anyone can provide an example of why return path is significant in PCB design.

    Thanks and Regards

  11. Closed: Need inputs on ddr supply voltage decreasing levels from ddr to ddr4

    Hi
    while going through suply voltages of various ddrs i came across this doubt(Silly really)
    are the supply voltages decreasing due to lower power(technology) or is it due to the logical one and...
