A flash ADC, or flash analog-to-digital converter, uses a parallel architecture with multiple comparators to convert an analog signal into a digital output in a single step. It employs a resistor ladder network to generate reference voltage levels, allowing it to compare the input voltage against these levels simultaneously. This design enables extremely fast conversion times, making flash ADCs suitable for high-speed applications, though they can be limited by power consumption and complexity as the number of bits increases.
Types Of ADC Are As follows: 1.Counter type ADC 2.Successive approximation type ADC 3.Flash Type ADC 4.Wilkinson type ADC
answer is 1. sigma delta ADC which is used to improve resolution of the ADC by oversampling
flash type ADC is fastest because in it change takes place simultaneously not sequentially time taken for conversion is 100 ns.

Analog-to-Digital Converters (ADC) can be classified into several types, including Successive Approximation ADC, Sigma-Delta ADC, Flash ADC, and Dual Slope ADC, each offering different trade-offs in speed, resolution, and complexity. Digital-to-Analog Converters (DAC) also have various types, such as Binary-Weighted DAC, R-2R Ladder DAC, Delta-Sigma DAC, and PWM DAC, which differ in their methods of converting digital signals to analog and their performance characteristics. These converters are essential in applications ranging from audio processing to instrumentation and communication systems.
The voltage at which the adc converts the signal.... it can also be called a limit of an ADC.
