Flash ADC (Parallel ADC) and Half-Flash ADC Explained

In this video, the working of Flash (Parallel) type ADC and Half-Flash ADC is explained. By watching this video, you will learn the following topics: 0:27 Flash ADC Working 7:07 Flash ADC Advantages and Disadvantages 8:26 Half-flash ADC working The Flash ADC: The Flash ADC (also known as parallel ADC) is fastest among all ADCs. The Flash ADC consists of 1) High-speed Comparator 2) Resistive Voltage Divider Network 3) Encoder Circuit In this video, the working of 3-bit Flash ADC is explained. Advantages of Flash ADC: It is fastest among all other ADCs and it is suitable for large bandwidth applications ( e.g Satellite Communication, High-Speed Data Acquisition for Oscilloscope, etc) Disadvantages: 1) High Power Consumption 2) Large Die Size 3) High Cost 4) Limited Resolution 5) High Accuracy of the Components (Resistors and Comparators) Half-Flash ADC: In applications where low power consumption and small die area is main criteria (for the same resolution with relatively good conversion speed) then Half-Flash ADC can be used. For N-bit Conversion, this Half-Flash ADC requires two (N/2) bit Flash ADC and one (N/2) bit DAC. In this video, the working of 8-bit Half-flash ADC is explained.
