In this video, the working of Dual Slope and Single Slope Integrating ADC is explained.
By watching this video, you will learn the following topics:
0:25 Dual-Slope ADC advantages and limitations
1:18 Working of Single Slope ADC
5:04 Limitations of Single Slope ADC
6:32 Working of Dual-Slope ADC
14:00 Conversion Time of Dual-Slope ADC
The Single and Dual Slope ADC:
These ADCs are integrating type ADC, meaning that they use the integrator for the conversion.
The Dual-Slope ADC provides good accuracy and high resolution
but it has sloe conversion time.
That's why it is not used for the data-acquisition, but due to its good accuracy and high resolution, it is used in the measurement instruments, particularly in the digital multimeters.

Why is the input signal getting integrated for 2^n, shouldn't it get integrated for 2^n-1?

@ee_57_shantanushukla35 Месяц назад

The counter will count from 0 to 2^N-1, implying that total count would be 2^N (for example for 0 to 3 total count is 4)

why should the reference voltage be integrated? before giving it as input to the comparator in single slope ADC

@er.parmeetrooprai5254 Год назад

@punitakumari187 3 года назад

Sir,in dual slope adc vin is unknown and we are integrating for fixed period of time ..so how counter will start count from 0000 to 1111 means 2^n-1? Bcz overflow become high when count exceeds from 1111.

@ALLABOUTELECTRONICS 3 года назад

Once the overflow bit becomes high during the time T1, the counter will get reset to 0000. That means during the time T2, it will start from 0000. I hope, it will clear your doubt.

@t.mahipalreddy5893 4 года назад

I didnt get u at switch is closed What happens??why we use switch over their??

@ajazamin9843 4 года назад

the circuit is reset before conversion after switching on the input voltage is selected and integrated over a period determined by RC time constant and a certain voltage output is obtained for a certain time period than switch is moved to select the reference voltage. as reference voltage is negative below zero it is integrated over time period till the output of integrator becomes zero

@kshitijyadav9101 Год назад

can you also provide the slides which you are using

@priyankasiwach5066 3 года назад

1:54 ,Why the reference voltage is integrated untill Vo=Vin?

@ALLABOUTELECTRONICS 3 года назад

As soon as the output of the integrator crosses the Vin, the output of the comparator becomes low. And further counting will stop. (As mentioned at 4:53) . And the integrator capacitor will get RESET. I hope it will clear your doubt.

@thevitruvianman9781 3 года назад

Does Vref have to be fed to inverting input? If yes, then why?

@ALLABOUTELECTRONICS 3 года назад

Yes, with that you will get the second slope. Please watch from 6:32 onwards, you will get it.

@trevor062 2 года назад

@mirovskii 9 месяцев назад

I couldnt understand the relation between the positive slope of the integrated output and the negative sign of the reference voltage. Why we said that the slope is positive because of the negative Vref? At the time 2.13 in the video.

@nthumara6288 6 месяцев назад

go and watch integrater vidio

@ShreyasBharadwaj 5 лет назад

The Dual slope example is quoted for Vmax of the ADC range. A fixed time period sampling of Vin with counter effective on T2 slope only will make the operation more practical. Otherwise an excellent video.

@ALLABOUTELECTRONICS 5 лет назад

The time duration for the input voltage is always fixed. The input signal will be integrated until the counter reaches (2^N -1). So, the time duration for Vin is fixed only.

@farhanupaul 4 года назад

Is the Vref also an AC signal with same frequency as Vin?

@ALLABOUTELECTRONICS 4 года назад

No, it's DC VOLTAGE. And it should be very stable.

@farhanupaul 4 года назад

@@ALLABOUTELECTRONICS But Vin is AC, and it will change polarity. So what will happen when negative cycle starts?

@ALLABOUTELECTRONICS 4 года назад

When ADC is used with only positive reference voltage then we need to ensure that, the input is positive only. If input is time varying or AC, then we need to provide the DC offset to ensure that it is positive. But some ADCs can be configured in the differential mode. And in such case, input can be applied from - Vref/2 to + Vref/2.

Shouldn't be the output of the integrator be positive when -Vref is applied?

Yes, it is positive. Please check at 2:23.

@shafiabid2522 4 месяца назад

But at 12:58 it says that the output of the integrator is still negative. Why?

@srilathamupparaju8576 4 года назад

Why we use integrator. normal counter type we don't use Any integrator so can you plz explain important of that integrator in this circuit

@ALLABOUTELECTRONICS 4 года назад

The different types of ADC use, different types of techniques for the conversion. The dual-slope ADC does not require any DAC for the conversion. (Unlike Counter type ADC) and it provides a good resolution. So, it is relatively cheap compared to other types of ADCs for the same resolution. And mostly it is found in the Digital Multimeters.

@3:12 how output of integrator Vo comes to Vin..in time T, bcoz as per input we only applied Vref

@ALLABOUTELECTRONICS 4 года назад

The input is Vref, but the output of the integrator is compared with the input of the comparator. At some T, the output of the integrator is equal to the Vin ( input of the comparator). I hope it will clear your doubt.

@mitulnagarsvnit1836 4 года назад

what is the vin ? is it sine wave or square wave?

@ALLABOUTELECTRONICS 4 года назад

Actual input to ADC system could be anything. The input to the ADC is the sampled value by the sample and hold circuit (as I mentioned in the introductory video). And SAH circuit should hold that value till the end of conversion. I hope it will clear your doubt.

@shaurya5harma 2 месяца назад

how T2 is N*Tc?

@ALLABOUTELECTRONICS 2 месяца назад

Here please do not get confused with the N with n-bit counter. N is the count value of the counter. n is the number of bits of the counter. I should have used different N for both n-bit counter and count value. That means T1= 2^n X Tc and T2 = N x Tc. I hope, it will clear your doubt.

@ALLABOUTELECTRONICS 4 года назад

Its shows the n clock cycles to reach the output to zero. During T1, the integrator integrates the input voltage. T2 shows the time required by the integrator to reach to 0V. That's n clock cycles (Where n is some counter output (between 0 to 2^N -1). I hope it will clear your doubt.
