ADC Type Characteristics Matching
This question requires matching four types of Analog-to-Digital Converters (ADCs) with their primary characteristics.
Matching ADC Types and Characteristics
- Flash type ADC (A): This converter uses parallel comparators to determine the digital output instantly. Its architecture allows for very high conversion speeds. Therefore, Flash ADC corresponds to the Fastest (II) characteristic.
- SAR type ADC (B): Successive Approximation Register (SAR) ADCs are widely used due to their good balance between speed, resolution, and power consumption. They are a common choice for many digital signal processing applications. Thus, SAR ADC matches with the Most widely used type (I) characteristic.
- Ramp type ADC (C): This ADC uses a simple counter and a Digital-to-Analog Converter (DAC) to create a voltage ramp. Its design is straightforward and easy to implement, making it the Simplest type (III) of ADC.
- Integrating type ADC (D): These ADCs measure the average value of the input voltage over a specific period. This integration process enhances noise immunity and provides high precision, leading to the Most accurate (IV) characteristic.
Conclusion
Based on the analysis:
- A matches with II (Fastest)
- B matches with I (Most widely used type)
- C matches with III (Simplest type)
- D matches with IV (Most accurate)
The correct matching is A-II, B-I, C-III, D-IV.
