摘要： A method is provided for adjusting the resonance frequency of a resonance circuit included in an electronic pen. The method uses adjusting means for adjusting the capacitance of an internal capacitor array and measuring means for measuring an alternating magnetic field generated by the resonance circuit. The method includes (1) a step of changing the state of a predetermined portion of multiple capacitive elements constituting the internal capacitor array, and (2) a step of changing, according to reference resonance frequency variations of the resonance circuit before and after the state change, the state of a portion or all of at least one capacitive element constituting the inner capacitor array other than said predetermined portion of the capacitive elements.

摘要： A superconducting circuit comprises a resonator and a Josephson junction. The resonator comprises an inductor and a capacitor. The inductor comprises a first terminal and a second terminal. The second terminal of the inductor is electrically coupled to a first terminal of the capacitor. A second terminal of the capacitor is electrically coupled to a first terminal of the Josephson junction. The terminal shared by the inductor and the capacitor is configured to be electrically coupled to an alternating current (AC) voltage source having a particular frequency and particular phase. The inductance of the inductor and the capacitance of the capacitor are selected to cause the resonator to resonate at a frequency and a phase that substantially match the particular frequency and the particular phase, respectively, of the AC voltage source to facilitate switching a state of the Josephson junction via a single flux quantum (SFQ) pulse.

摘要： A tunable impedance multiplier with high multiplication factor is described. A single externally connected resistor is used and the multiplier is free of passive elements. The circuit can realize a positive or a negative impedance multiplier. Applications of the design to low and high pass filters are also presented. The simulation and experimental results show that the new design enjoys a multiplication factor above 400 at 2 Hz-to 7 MHz.
