How does a flash type ADC work?
How does a flash type ADC work?
Flash Type ADC is based on the principle of comparing analog input voltage with a set of reference voltages. To convert the analog input voltage into a digital signal of n-bit output, (2n – 1) comparators are required. The non-inverting inputs of all the three comparators are connected to the analog input voltage.
Where are flash ADC used?
Abstract: Flash analog-to-digital converters, also known as parallel ADCs, are the fastest way to convert an analog signal to a digital signal. Flash ADCs are ideal for applications requiring very large bandwidth, but they consume more power than other ADC architectures and are generally limited to 8-bit resolution.
What are the advantages and disadvantages of flash type ADC?
Block diagram of Flash ADC The advantage of this converter is the speed with which one conversion can take place. The disadvantage of the Flash ADC is the area and power requirements of the 2 N-1 comparators. The speed is limited by the switching of the comparators and the digital logic.
What is the advantages of using flash type ADC converter?
Explanation: Flash type ADC has the advantage of high speed as the conversion takes place simultaneously rather than sequentially. Typical conversion time is 100nanosecond or less. Explanation: The number of comparator required almost doubles for each added bit.
What is ADC and DAC?
In electronics, a digital-to-analog converter (DAC, D/A, D2A, or D-to-A) is a system that converts a digital signal into an analog signal. An analog-to-digital converter (ADC) performs the reverse function.
What are the applications of DAC?
DACs are commonly used in music players to convert digital data streams into analog audio signals. They are also used in televisions and mobile phones to convert digital video data into analog video signals. These two applications use DACs at opposite ends of the frequency/resolution trade-off.
What is casting in Java?
The casting is nothing but the conversion of one data type to another data type. This casting is of two types, these are static casting and dynamic casting. This static casting is used for the data type conversion.
What is static casting in SystemVerilog?
SystemVerilog casting: Casting in SystemVerilog (static casting) (‘) : The cast (‘) operation can change the data type. For applying a cast to the data type that must be closed in parentheses or within concatenation or replication.
What is the difference between static casting and dynamic casting?
The cast (‘) operation can change the data type. For applying a cast to the data type that must be closed in parentheses or within concatenation or replication. The static casting can also be applied for the user defined types. The dynamic casting will be done by using the system task called $cast.
What are the different types of casting defects?
Metallurgical defects Metallurgical casting defects come in two types, they are, Hot tears and hand spots. These types of casting defects may fall in any of the two. Read: Foundry work and Processes
