What does comparator do in ADC?
What does comparator do in ADC?
A comparator is normally used in applications where some varying signal level is compared to a fixed level (usually a voltage reference). Since it is, in effect, a 1-bit analog-to-digital converter (ADC), the comparator is a basic element in all ADCs.
How many comparators are required for 8-bit ADC?
An 8-bit ADC, for example, will require 256 comparators (28 = 256).
How does ADC dual slope work?
The dual slope ADC mainly consists of 5 blocks: Integrator, Comparator, Clock signal generator, Control logic and Counter. The control logic resets the counter and enables the clock signal generator in order to send the clock pulses to the counter, when it is received the start commanding signal.
How does comparator work java?
Comparator , represents a component that can compare two objects so they can be sorted using sorting functionality in Java. When sorting e.g a Java List you can pass a Java Comparator to the sorting method. The Comparator is then used to compare the objects in the List during sorting.
How many comparators are used in 2 bit ADC?
If we now create a 2-bit ADC, then we will need 22– 1 which is “3” comparators as we need four different voltage levels corresponding to the 4 digital values required for a 4-to-2 bit encoder circuit as shown.
How many comparators does a 12 bit flash ADC?
4096 comparators
A 12-bit flash converter requires 4096 comparators, while proposed technique reduces number of comparator requirements to only 256 for 12- bit conversion.
What is dual ADC?
In dual slope type ADC, the integrator generates two different ramps, one with the known analog input voltage VA and another with a known reference voltage –Vref. Hence it is called a s dual slope A to D converter.
Why dual slope ADC is most accurate?
Dual slope integration type ADC is the most accurate type of ADC because of non-dependency on variation in component values caused by noise.
