The parallel comparator/flash adc
WebbFlash ADCs are also prone to sporadic and erratic outputs known as "sparkle codes." Sparkle codes have two major sources: Metastability in the 2N-1 comparators, and thermometer-code bubbles. Mismatched comparator delays can turn a logical 1 into 0 (or vice versa), causing the appearance of "bubbles" in an otherwise normal thermometer …

WebbI. INTRODUCTION » An analog-to-digital converter (A/D or ADC) produces a digital output (Bits) corresponding to an analog input voltage sample. » Flash ADC Consists of a series of comparators, each one comparing the input signal to a unique reference voltage. Webb13 jan. 2024 · Flash ADCs are considered the fastest type in ADC due to its parallel process by using a large number of comparators . The N-bit flash ADC requires resistors and comparators and one encoder . Each comparator has a reference voltage that is compared with an analogue input voltage.
