Compact oscillating devices can be realized by exploiting the insulator-to-metal transition of VO 2 (IMT). Coupled oscillators can be locked in frequency and phase through connections realized with resistors or capacitors. Oscillatory neural networks based on VO 2 devices are researched as neuromorphic computing hardware for image recognition applications  ,  . Physical demonstrations of large networks of coupled oscillators are yet hindered by the device-to-device variability  . In this work, we present a frequency-injection scheme which allows additional tuning and control of the oscillator network comprising non-ideal VO 2 devices.
