Exceptional Points in Gyrator-Based Circuit and Nonlinear High-Sensitivity Oscillator
Alireza Nikzamir, Kasra Rouhi, Alexander Figotin +1
We present a scheme for high-sensitive oscillators based on an exceptional point of degeneracy (EPD) in a circuit made of two LC resonators coupled by a gyrator. The frequency of o…
