Abstract
Disclosed are example embodiments of a circuit comprising a first inductor-capacitor (LC) loop, a second LC loop having at least one of a series connection or parallel connection to the first LC loop, and a gyrator coupled between the first LC loop and the second LC loop. In an example, the first LC and the second LC loop each include an inductive element (L) and a capacitive (C) element coupled to each other in series. In another example, the first LC and the second LC loop each include an inductive element (L) and a capacitive (C) element coupled to each other in parallel.

A circuit comprising:
- a first inductor-capacitor (LC) loop;
- a second LC loop having at least one of a series connection or parallel connection to the first LC loop;
- and
- a gyrator coupled between the first LC loop and the second LC loop,
- wherein the first LC loop and the second LC loop each include an inductive element (L) and a capacitive (C) element coupled to each other in series.
A sensor whose electronic circuits comprise:
- a plurality of LC loops;
- and
- a gyrator coupled between a first LC loop and a second LC loop of the plurality of LC loops, wherein an inductance and a capacitance of each of the plurality of LC loops and a gyrator resistance is selected such that the sensor operates at, or close to, an exceptional point of degeneracy.
