Self-sustained Low Power Oscillator Based on Vibrating Body Field Effect Transistor

Mihai Adrian Ionescu

The operation of a vibrating body field effect transistor (VB-FET) near pull-in is exploited to experimentally demonstrate a self-oscillating device. The positive feedback mechanism is triggered at the onset of inversion in a depleted VB-FET channel, near ...
