US Patent 7714267 Intensity detector circuitry using a cascade of gain elements

A system is described that may determine an intensity measure. In certain example embodiments, a system may include circuitry for receiving and circuitry for assessing. The circuitry for receiving may receive an input signal at an input of a first gain element of a cascade of N gain elements. The circuitry for assessing may assess an intensity in response to one or more times associated with one or more output signals of the cascade of N gain elements satisfying one or more threshold values.
