In this video series we look at ways or tips to improve ADC measurement accuracy and resolution. In part 1 define what accuracy and resolution is and different types of error that can affect ADC measurements. We also look at the importance of using an accurate ADC reference voltage and why you want to scale the range of the signal you are measuring to the ADC's range.

Thanks. Great tutorial. There are actually quite a few 1, 2 or 3 bit ADCs used in RF front-ends like GPS receivers.

Awesome tutorial. Easy to understand and we'll explained. Looking forward to watching the followings parts.....

Thanks. Taking a measurement is more complex than one might at first think.

what if i have to measure 0.1mV signals what kind of ADC should I use with 24 bit resolution

@user-mj3ef 5 жыл бұрын

At 17:54 I think you mimic line regulation not load regulation. Because you add squarewave to the input of regulator.

No I meant that I was simulating the output of regulator that was being used for ADF reference. Sorry if that was not clear

you divide by 1024 as that is the number of states in 10 bits. You would start counting at zero to 1023 (and still have 1024 states).

@ForceTronics 3 жыл бұрын

You don't count the 0 state when calculating ADC voltage so that is why with a 10 bit ADC you use the 1023 value to calculate the voltage. If 10 apples costs $5 and you wanted to know what 4 apples costs you would not do your ratio calculation with 11 apples. Cost of 4 applies equals 4 /10 x $5

@@ForceTronics If you use bananas you have 4 for 2^2.

@@Zorgens Haha correct, but if you say there are 2^2 states of having bananas: you can have 0, you can have 1, you can have 2, and you can have 3.

The video was exactly correct, e.g. 5V in 10 bit can measure down to the nearest 5V/1023 = 4.89mV. Conversely the guy above (Digger D) was also correct in that there are 1024 states, and zero is one of those states. I don't think these two statements are different.
