Abstract
An oscillator outputs a stable oscillation. The oscillator includes an amplifier, a carbon nanotube (CNT), and a power supply. The CNT extends along a resonance axis. A first end of the CNT is disposed along the resonance axis such that the first end is open. A second end of the CNT is disposed along the resonance axis and be operably coupled to the amplifier. The CNT generates a stable oscillation in response to a voltage. The amplifier includes a super-lattice castellated field effect transistor (SLCFET). The power supply applies the voltage to the oscillator.
