Abstract

Embodiments of the present disclosure provide a system for detecting and precisely measuring information content of one or more environmental conditions. The system may include a plurality of oscillator circuits that are coupled together. The coupling of the oscillator circuits generates an output signal having a pattern of amplitude and frequency. The pattern of amplitude and frequency changes as one or more values of the environmental condition(s) change.

2 . The system of claim 1 , wherein each of the plurality of oscillator circuits comprises multiple negative resistance non-linearities that provide multiple stable equilibriums.

3 . The system of claim 2 , wherein the system is devoid of a separate and distinct reference source.

4 . The system of claim 2 , wherein one or both the multiple negative resistance non-linearities or the multiple stable equilibriums of the plurality of oscillator circuits are different.

5 . The system of claim 2 , wherein one or both the multiple negative resistance non-linearities or the multiple stable equilibriums of the plurality of oscillator circuits are the same.

6 . The system of claim 1 , wherein the plurality of oscillator circuits are electromagnetically coupled together.
