Architectures — A simultaneous A/D converter (all comparators acting at once) is also known by which common name?

Introduction / Context: ADC architectures vary in speed and complexity. The fastest class compares the input to many thresholds simultaneously using a bank of comparators and a priority encoder. Knowing the common names aids datasheet reading and part selection.Given Data / Assumptions:

• “Simultaneous” means all comparisons occur in parallel.
• Resolution is typically modest (e.g., 6–8 bits) due to comparator count scaling.
• Emphasis is on ultra-low latency.

Concept / Approach: The parallel-comparator design is widely called a “flash” ADC because the conversion completes in a few gate delays, effectively in a flash, instead of iterating bit decisions sequentially like SAR or integrating converters.Step-by-Step Solution:
