Something new occurred to me regarding your audio… The effect that I presume is clipping, may be caused by echo in the room your recording in, especially is the surfaces are mostly bare. If this is a problem, and you want to fix it, there are a lot of different ways. But a quick one would be to hang some kind of cloth on your walls. Although I have a hunch that filling a large mesh net with packing peanuts, or some other loose, light material, and attaching it to your ceiling would work pretty good. I don't know you opinion on this, so I'm sorry if I seem pushy or something. Just trying to help…
A flash ADC uses comparators with a settling time of 40ns and a 3 stage digital decoder made of gates possessing a delay of 2ns.Determine the conversion time of ADC ?
For gate perspective all the topics have been covered. But I am going to cover other ADCs like sigma- delta and pipeline ADC, and importance of performance parameters of the ADC. I think it will be useful in general to everyone one who are going to use ADC and DAC in some application.
Typically for ADC, the reference voltage is specified in the data sheet. ( like 3.3 v, 5V, 9V, 12V etc)In your case, you need a reference voltage more than 6V. For example, if ADC supports up to 9V, then you can use that voltage. But again that depends on the ADC.
@@ALLABOUTELECTRONICS Is it the type we use for signal processing and control? because the delay caused by standard ADC's can distort a real time signal that needs to be processed right then and there because say a temperature signal is a sine wave, it could appear distorted when inputted this way due to the sequential part that varies depending on values.
It is in fact, other way around. Imagine just 1-bit comparator. To compare the voltage, using a voltage divider, you need at least two resistor. That means for 1-bit, you need 1 comparator and 2 resistor. That is 2^1 -1 comparator and 2^1 resistor. The same is true for n-bit flash adc.
Yes it's another type of ADC. It is typically used where high resolution is required. ( But speed is not that important). Someday, will also cover that on the channel.

Your efforts are commendable and the knowledge you share is priceless👌🏼
Thanks man. You helped finishing my pre-lab assignment
Thanks! This gives me answers to all the questions on this subject that I had.
Thank you so much! I might just clear one subject coz of you guys:)
What an amazing video. It helped me a lot. Good grahics too. Well earned view and thumbs up :)
it saving my project. thanks
Hermano, tus vídeos son excelentes
Muchas gracias 👌🏻
Superrr brooo well said..👌👌 keep gng on always with more useful content and more videoes..we always love ur videoes and also love u..😍😍😍😍😍😍
Excellent presentation
u helped me a lot for exam😄
thanks for the video, I really understand better this topic :)

Just Superb 👌👌
For the second flash adc onwards it is rather difficult to change to digital (too small) , 8:37
Thank you so much for this video
Sir , In the half flash adc ,can we get the first 4bits of the output by directly from the first ADC ?
Yes, that's exactly how we get the 4 MSBs of output. (As I have mentioned at 9:13)
Ok sir thanks for the quick response ❤️

Sir is ADC and DAC series over for gate syllabus ?

Awesome explaination👌👌
I'm not getting an output one of the comparator when applying the input voltage of 5volts. Instead of that I'm getting 10volts.
Would you please elaborate how you have connected the circuit?
Good Job.. Superb....
Hi sir, on what basis we should select vref , if my input signal is varying from 2v to 6v
Typically for ADC, the reference voltage is specified in the data sheet. ( like 3.3 v, 5V, 9V, 12V etc)In your case, you need a reference voltage more than 6V. For example, if ADC supports up to 9V, then you can use that voltage. But again that depends on the ADC.
How it is 1v after R divides by R + 7R
Thank you sir
I have a doubt that for this encoder we need 8 inputs but from 7 comparators we are giving 7 inputs to encoder then what about 8th input.
Another one is ground
7 comparators is pretty expensive though!
That is why flash ADCs are not cheap.

how no. of comparators is 2^n- 1? it should be 2^n only
Just look at the diagram of 3 bit flash ADC. It requires 7 comparators.
Every ADC should pick flash and maybe ignite
Very very 😊 🫂 🙏 😊 🫂 🙏 😊 🫂 🙏 thanks
Awesome
In our they teach me 8-comparator and 7resister .sir

That is 2^1 -1 comparator and 2^1 resistor. The same is true for n-bit flash adc.
Sir, What is sigma delta ADC!
Is it another kind of ADC!
I haven't found in our channel ALL ABOUT ELECTRONICS!!!
Yes it's another type of ADC. It is typically used where high resolution is required. ( But speed is not that important). Someday, will also cover that on the channel.
@@ALLABOUTELECTRONICS okay Sir!! Thank you.
Maza nahi aaya
easier to understand is this: flash adcs are meta and half flash adcs not, Kappa
