All bits divide the voltage with 2 therefore the voltages for the 6 bits from MSB downwards are: Bits 5 4 3 2 1 0 Voltage 10 5 2.

Other equivalences, Equivalences: In this following miscellaneous equi The precision of an ADC is determined through two key elements i. This avoids the aliasing or overlapping of the signals to retain all the information and avoid data distortion or loss.
The samples are then assigned finite levels by a process called quantization and followed by the encoding of the signal into binary format. It is the difference between the assigned value and the closest available digital value at each sampling point. The formula for the quantization error is. For example, let say the reference voltage is 16 volts and the number of bits is 4 then quantization error is. It depicts that any input voltage less than 1 volt will be considered as zero.
Any voltage greater than 1 volt will change the ADC output voltage. This introduces an error and known as quantization error. The resolution of an ADC is based on the number of bits which tell us about the number of levels an ADC can produce and quantize the input analog signal.
The general formula is. Where N represents the number of bits. The higher the resolution, the more accurate are the resultant signals. For a 4-bit ADC, the resolution will be Though ADC is implemented using various techniques these days, this article will focus on the Successive Approximation method. It is the most frequently used ADC technique for general applications. The ADC comprises a comparator, digital to analog converter, register, and a control circuit.
The schematic is shown below:. At the point when the new conversion begins, the sample and hold circuit samples the input voltage and then this sampled signal is compared with the output signal of the digital to analog converter. To grasp the concept, consider a 4-bit ADC with a sampling rate i. We take the comparator reference voltage as16 Volts.
Whenever the new transformation begins, the successive approximation register sets the most significant bit to 1 and all others to zero. So the output voltage of the DAC corresponding to the stated digital code and reference voltage of 16 turns out to be. This is the threshold voltage to which the input voltage will be compared. Thus, the output voltage of the comparator will change the output value of the successive register.
