- 2. In a flash analog-to-digital converter, the output of each comparator is connected to an input of a:
Options- A. decoder
- B. priority encoder
- C. multiplexer
- D. demultiplexer Discuss
- 3. Sample-and-hold circuits in analog-to digital converters (ADCs) are designed to:
Options- A. sample and hold the output of the binary counter during the conversion process
- B. stabilize the comparator's threshold voltage during the conversion process
- C. stabilize the input analog signal during the conversion process
- D. sample and hold the D/A converter staircase waveform during the conversion process Discuss
- 4. Which is not an analog-to-digital (ADC) conversion error?
Options- A. differential nonlinearity
