Which of the following is the fastest type of ADC?(a) Successive approximation conversion(b) Flash conversion(c) Delta encoded conversion(d) Pipelined conversionThe question was asked in an interview.This intriguing question comes from Data Conversion in portion Digital Communication Techniques of Avionics

Answer»

Correct choice is (b) FLASH conversion

Easy explanation: The flash converter PRODUCES an output as fast as the COMPARATORS can switch and the signals can be translated to binary levels by the logic circuits. Comparator SWITCHING and logic PROPAGATION delays are extremely short. Thus, flash converters are the fastest type of A/D converter.
