Abstract
Does innovation in ADC design follow a straight-line progression? Should the pervasive use of figures of merit (FOMs) be encouraged? It is the author contention that a closer look to the symbiosis between converters applications and converters technology suggests a substantially more complex picture deserving attention. Two emerging ADC classes, the time-domain converters and compressive sampling techniques, are examples of a different view on this topic.

Notes
- 1.
A theoretical upper bound of 192 dB is set by the thermal noise limits. This points to the challenge of going higher [3].
- 2.
While we will refer to “time” for brevity, let it be understood that we mean “time intervals.”
- 3.
A time-domain quantization error.
- 4.
And we have already emphasized how time-domain resolution promises to benefit from CMOS scaling when we talked about TDCs in the previous section.
