Patent number: 11431291Abstract: A nano-oscillator device includes a switching element configured to be switched to an ON state at a threshold voltage or above and switched to an OFF state below a holding voltage; and a load element connected to the switching element in series. In the nano-oscillator device, vibration characteristics are implemented by using a switching element and a load element connected thereto in series. Also, the oscillation frequency of the output waveform of the oscillator may be adjusted in real time according to a gate voltage by using a field effect transistor serving as a load element. Using a synchronization characteristic in which the oscillation frequency and phase are locked with respect to an external input, it is possible to implement a computing system based on a network in which a plurality of oscillator devices are coupled.Type: GrantFiled: September 7, 2021Date of Patent: August 30, 2022Assignee: KOREA INSTITUTE OF SCIENCE AND TECHNOLOGYInventors: Suyoun Lee, Seon Jeong Kim, Jong-Keuk Park, Inho Kim, Kyeong Seok Lee, Gyu Weon Hwang, Joon Young Kwak, Jaewook Kim, Yeonjoo Jeong, Jongkil Park
