Define Flash Analog to Digital Converters?
Parallel flash ADCs transform the analog input voltage faster as compared to other types of ADCs. They compare the voltage in parallel along with a series of comparators which are attached to a resistive network.
Their main benefit is that they work very fast as they produce a digital output in a single cycle. They are the just one type of converters that can be used for very high-speed conversions like video processing. Their drawback is that the resistors in the network should be matched and laser-trimmed for accuracy. Due to the exponential increase in components, flash ADCs are extremely expensive if more than 6 bits are required.
2 n -R D/A CONVERTER An n-bit 2 n -R D/A converter needs 2 n resistors of equal value R and (2 n+1 -2) analog switches. A 3-bit 2 n -R D/A converter is shown in Figure, which
