A Novel Hybrid PLL Frequency Synthesizer Using Single Electron and MOS Transistors

This paper proposes a novel hybrid phase-locked loop (PLL) using single electron transistor (SET) and metal-oxide-semiconductor (MOS) transistor. A novel hybrid voltage controlled oscillator (VCO) and hybrid logic gates using SET and MOS transistors are used to construct the hybrid PLL. The hybrid VCO has several advantages: a wide frequency tuning range, low power dissipation and large load capability. We study the performances of the hybrid PLL circuit by HSPICE simulator. Simulation results demonstrate that the hybrid circuit could well operate as a PLL at room temperature. The power dissipation of the PLL circuit is lower than 10uW.
