Voltage tunable oscillator using bilayer graphene and a lead zirconate titanate capacitor

  • US Patent No. 9252704
  • Issued: February 02, 2016
  • Status: Active

A voltage controlled oscillator comprising a substrate and a bilayer graphene transistor formed on the substrate. The transistor has two signal terminals and a gate terminal positioned in between the signal terminals. A voltage controlled PZT or MEMS capacitor is also formed on the substrate. The capacitor is electrically connected to the transistor gate terminal. At least one component is connected to the transistor and capacitor to form a resonant circuit.
