Abstract
A voltage controlled oscillator includes a split ring resonator (SRR) configured to have meta-material characteristics fabricated on a board, and an energy compensation circuit configured to cause resonant oscillation of the SRR. The energy compensation circuit is fabricated in the form of an integrated circuit.
Claims8
A voltage controlled oscillator, comprising:
- a split ring resonator (SRR) configured to have meta-material characteristics fabricated on a board;
- and
- an energy compensation circuit configured to cause resonant oscillation of the SRR, the energy compensation circuit being fabricated in the form of an integrated circuit.
A voltage controlled oscillator, comprising:
- multiple split ring resonators (SRRs) configured to have meta-material characteristics fabricated on a board, the SRRs operating at different frequencies;
- an energy compensation circuit configured to cause resonant oscillation of the SRR, the energy compensation circuit being fabricated in the form of an integrated circuit;
- and
- multiple switches configured to perform a switching operation to allow any one of the SRRs to make resonant oscillation by the energy compensation integrated circuit.
